Which companies use the Python language

Programming languages: These are particularly in demand

The digitalization - that much is certain - is fundamentally changing the world of work. Anyone who wants to help build this future will arrive Programming languages not over. Programmers and developers are the architects of modernity. At the same time, many are asking: What are the most important programming languages? Which programming language should I learn and master? What about Java, C, Kotlin, or Python? In fact, very different tools are hidden behind the sometimes cryptic language names. We tell you in one Programming languages ​​comparisonwhich modern languages ​​are important, what for and with what you have good career opportunities ...

Definition: what are programming languages?

Programming languages ​​are used to guide computers through certain Calculation rules (so-called Algorithms) instruct them to process, structure and translate the entered data into results in order to achieve a solve a given problem.

Depending on the machine and the problem, there may be different Programming languages ​​are used that are either more complex or deliberately simpler and therefore more user-friendly. In addition, he kept playing Speed ​​comparison plays a big role in the question of which language can prevail and which cannot.

So evolved over time different generations of programming languages ​​that differ greatly in terms of comprehensibility, speed and versatility.

A clear one Ranking, which uses a top 10 to illustrate which most important Programming language is therefore difficult to pin down, but depends on the industry and the problem: Should the computer just be a simple one, for example Crossword puzzle solve or a complex Production process Taxes. Nevertheless, from industry-specific Lists Read out clear priorities, which, however, can often change.

There are among experts differentiated distinctions such as between the terms "Programming language" and "Script language" (e.g. Javascript). In this context, it also plays a role whether the system can run on its own or not.

The simplicity For the sake of this article, however, these differences are to be summarized under the generic term “programming language”, since the primary aim is to create a insight into the topic and the Use of learning programming languages ​​without confusing too much with technical details.

Learning Modern Programming Languages: No Nerd Territory

Sure, who as a programmer, Front end- If you want to work as a developer, IT security analyst or data scientist, you should have a command of programming languages. But also apart from the IT jobs technical skills increasingly important:

In insurance, for example, in public administration and in schools. Even (prospective) teachers and parents are therefore well advised to familiarize themselves with Codes and Coding too busy. Because: According to calculations by the London School of Economics (LSE), it is long-term every second job is threatened by digitization. At the same time, employees who still have a command of a programming language for the job they have learned are in increasing demand: to modify an online shop or an add-on for an application to write, are unbeatable additional qualifications.

Which programming language for which industry is used is not stipulated. So what is the best programming language to learn? The somewhat unsatisfactory answer: It depends ...

  • Every now and then, for example, turns up Visual Basic as language. Visual Basic is popular with Microsoft and is therefore still used relatively often in this environment. However, the successors are already in the starting blocks at Microsoft. However, if you already know the language, you will quickly find friends in the Microsoft universe.
  • Assembly Language is probably the easiest way to communicate directly with the processor. However, this has its price: The language is difficult to learn and is primarily something for developers who want to work in the field of wearables and smart devices.
  • Anyone who deals with the Internet will turn to Pearl don't get around. Developed in the late 1980s, Perl has been around for a few years. However, the language is still one of the favorites of web developers. It's great for closing gaps and fixing bugs.
  • To program apps is against it Delphi Object Pascal or Swift (probably even better both) a good condition.
  • In the field of AI, the artificial intelligence scientists like to pick up MATLAB back. The language is created to map algorithms.
  • Data scientists and statisticians, on the other hand, like to use R.. Short name, but powerful: if you believe the rumors, the language is also being used more and more on Google.

In addition, many other languages ​​are used in different industries. Some last for a long time, others disappear again quickly and still others come as brand new Niche languages on the market. As currently ballerina - as a modern programming language for everyone who deals with microservice architectures.

Nobody knows exactly where the market and its requirements will ultimately develop. However, it is undisputed that employees who have mastered a programming language on the Labor market of the future will certainly have good cards.

Programming languages ​​list: A comparison of important programming languages

But let's go into a little more detail. You can find them again and again on the internet Programming language rankings the current main or most popular Programming languages ​​that - supposedly - guarantee a job or that developers should definitely learn.

We don't want to say that across the board. Because that depends above all on your future plans and career aspirations or on the specialization and application you are aiming for. That's why we chose one Programming languages ​​listwhich does not represent any hierarchy. Rather, the codes are sorted alphabetically. There is also a profile for each of the programming languages ​​- with areas of application, job prospects or level of difficulty. This is the best way to find out which language suits you and your goals ...

Overview of the programming languages

  • Language: C

    • Application: C is the basis of C ++ and is used in many areas. Gladly when programming operating systems or in system programming.
    • Job prospects: C is a basic language that is widely used and therefore always sought after. Anyone who knows C as a programmer - and certainly not as a "normal" employee - does not have to worry.
    • Difficulty level: Relatively complex, but C provides good insights into the structure of (object-oriented) programming languages.
    • Conclusion: Well worth considering. Although the effort is significantly higher than with Python, if you master C, you will quickly learn C ++.
  • Language: C ++

    • Application: C ++ is often used by the "Big Three" Google, Facebook and Apple. It is used for machine-level programming.
    • Job prospects: C ++ is an extension of C that can also be used for object-oriented programming. The language is one of the most widely used in the world.
    • Difficulty level: C ++ very difficult to learn due to its immense size.
    • Conclusion: Not suitable for beginners who want to get an overview.
  • Language: C # (pronounced: C-Sharp)

    • Application: Important for all things that are related to Microsoft (Microsoft has the rights to this language). and for .NET Framework. As well as for computer games and operating systems.
    • Job prospects: Direct competitor to Java. Still widespread. Best prospects on the job market with C # too.
    • Difficulty level: Difficult to learn.
    • Conclusion: More interesting for developers, less for non-IT people who are only interested in how programming languages ​​work.
  • Language: Haskell

    • Application: Used for functional programming, but is rarely used. Particularly interesting for industries that require the precise mapping of mathematical algorithms.
    • Job prospects: According to a survey by jobsQuery, IT specialists who have mastered Haskell can look forward to the most salary. However, there is one thing you should keep in mind before you start learning this language with enthusiasm: the demand for Haskell is very low and therefore the selection of interesting jobs is relatively limited.
    • Difficulty level: Very difficult to learn, relatively confusing syntax. Not suitable for beginners.
    • Conclusion: If you want to learn programming, you should look for another language.
  • Language: Java

    • Application: Java offers a wide range of uses. Originally intended for cell phones and mobile devices, it is now used for animated websites, cloud computing, apps for Android and business software.
    • Job prospects: Java is a language that does not seem to be going out of style and occupies one of the top places in the rankings every year. This also applies to the merit of the programmers who speak this language.
    • Difficulty level: Java can be expanded indefinitely (of course only within the syntax of the language). This makes the language very interesting because it can be adapted to any number of applications. This can be a real challenge for beginners. However, advanced users benefit from the large number of Java frameworks.
    • Conclusion: Java is one of the imperative languages ​​and thus makes it easier to learn C and C ++ - they also belong in this category.
  • Language: Javascript

    • Application: Web development and apps.
    • Job prospects: Even beginners who should program their own interactive webpage without great effort are well advised to use Javascript. For this reason, this programming language is also used in a large number of service offices dealing with web development. If only because there are so many developers who know this language and many web applications are programmed in Javascript. Javascript is not only popular with web developers. Admins, data scientists and desktop developers also like to use this programming language.
    • Difficulty level: Learning well is a good way to get started.
    • Conclusion: Real option for novice programmers.
  • Language: Kotlin

    • Application: Kotlin is also used in web development, it is a pragmatic programming language that can be used as a complement to Java.
    • Job prospects: So far it has been beaten a bit in the ranking, but Google has announced that it will make it a native language for the mobile OS. Therefore, Kotlin is predicted to have good development potential.
    • Difficulty level: Slightly shorter and clearer than Java. In contrast to Java, where you have to rely on the community for questions, Kotlin is a company that publishes tutorials and guides.
    • Conclusion: A real alternative to Java for beginners. The scope is similar, but Kotlin is easier to learn.
  • Language: PHP

    • Application: Used in web development.
    • Job prospects: On the net it is hardly possible without PHP. CMS solutions are also often programmed with it. This affects a great many areas. The frequently used TYPO 3 also works on the basis of PHP. Since PHP has an extremely wide range of applications, you can earn a lot with it. Because especially the popular areas of web development can be covered with it.
    • Difficulty level: PHP is a scripting language that is based on Perl and C.
    • Conclusion: who something to do with media want to do, consider learning PHP.
  • Language: Python

    • Application: Typical all-rounder that is very popular with Google and Facebook.
    • Job prospects: Good prospects, as the programming language is often represented.
    • Difficulty level: Python is relatively easy to learn because it is a clear language with a style that is easy to understand. Developers also like to use it. So it actually has a practical relevance. Since Python stays that way, there are a number of free materials and even complete online tutorials that make it much easier to get started with the world of this programming language.
    • Conclusion: Similar to Java, Python is suitable for a large number of areas of application. Python is therefore a good choice if you want to learn to code. You can get the first results very quickly.
    • Language: SQL

      • Application: Primarily a database language and ideal for data structures in relational databases.
      • Job prospects: Often searched for by companies.
      • Difficulty level: Relatively difficult to learn as the programming language is very complex. However, the demand is high and so the effort can be worthwhile.
      • Conclusion: Not very suitable for beginners. However, if you already speak a language, you can try SQL.

If you still have doubts, you can of course also refer to the current ones mentioned above Programming language rankings orientate. An overview of the current state of affairs can be found here and here, for example.

Programming languages ​​types: declarative or imperative?

There isn't just that a Programming language, but many different ways of communicating with the machine. There are two large groups:

  1. The declarative languages. Here the programmer describes what should be done. Declarative programming also includes logical and functional languages. Well-known representatives are SQL and HTML.
  2. The imperative languages. It's about how to solve a problem. Examples of an imperative programming language are Pascal, Haskell and C. Object-oriented, structured and procedural languages ​​such as Java or Kotlin also belong in this category.

Knowing a single programming language is often no longer enough for developers today. Those who want to work in this area should choose between the two big ones Paradigms of declarative and imperative languages. Not least in order to be able to solve a problem from different sides.

Programmer: Where else can you find them?

If the skills of a particular occupational group are so in demand that other employees want to learn these skills, this usually does not mean anything good for employers. Because that means that the appropriate Skilled workers rare are.

With the classic incentives such as company cars or employee discounts, no programmer can be attracted. So what can employers or hiring managers do to bring out one of the coveted talents at one practically empty-swept job market recruiting who ideally also speaks several programming languages?

Well, you could of course post a job advertisement in the in-house job board Karrieresprung.de switch. But there are not only job advertisements there. Much more subtle (but no less effective) is the path as the “godfather” of one or more of the round 300 job profiles.

There you could, for example, sponsor the professional profile “programmer”. Advantage: You not only link your logo and company profile with it searched and often visited specialist articles. As a sponsor, your own job advertisements are primarily displayed there. Or to put it another way: Your job offers will become more visible for aspiring programmers as an employer - and immediately clickable. So ideal for employers who don't yet have applicants on their radar ...

Other ways are ...

  • Hackathons

    At this event, young talents and old hands from the hardware and software industry gather to jointly program useful or simply funny software and manufacture corresponding products. Employers can come into contact with potential employees in a very relaxed manner. This is also expected at hackathons and so many participants now have business cards with them when they go to an event.

  • Special IT tools

    Many speak of the fact that programming languages ​​belong to the future. But that is forgotten when it comes to recruiting. There are special tools only for IT professionals: RecruitEM For example, searches for suitable candidates in social networks such as Google+ or LinkedIn, but also in classic IT networks such as Stack overflow and GitHub.

  • Search actively

    Applicants who have mastered one or more programming languages ​​rarely need to apply in the course of their careers. Usually they are searched for. A call from the headhunter, however, is not the preferred communication medium for IT people.You would much prefer if the potential employer - who is surprised - gets in touch with you by e-mail.

  • Qualify yourself

    If you simply cannot find a suitable employee as an employer, you can further qualify your own staff. Ideally, you have exactly what you need, the employee is happy about the further training, is more motivated and feels connected to the company in the long term. What more do you want?
