Best programming languages to learn in 2018

Technology is evolving rapidly and it’s pretty hard for a software developer to decide which new programming language to learn. You never know how things are going to evolve in life, and it’s difficult to make the right choice regarding a new programming language because it will affect the evolution of your career.

This article is meant to be a guide for programmers that want to choose the right language career path in 2018.

This is not a top of “the coolest programming languages” but rather a top of the most sought out technologies this year and the ones that are making the greatest impact on software engineering.

Before starting to learn a new language, a software developer usually takes into consideration

  • What financial benefits will this new language will ensure(salary)
  • How popular is this language
  • If it has a tendency to become more in-demand in the future
  • If this new language is easy to learn and pleasant to work with

Let’s see which programming languages fit into these criteria:


For the fifth year in a row, JavaScript is the most commonly used programming language, according to StackOverflow’s annual survey, with 62.5% of respondents claiming to use it.

JavaScript is an essential tool for frontend web development. For many years, JavaScript was the most popular programming language, used by over 80% of developers and by 95% of all websites for any dynamic logic on their pages, according to StackOverflow.

Stack Overflow’s co-founder Jeff Atwood says that “any application that can be written in JavaScript will eventually be written in JavaScript”. And most developers agree.

One of the reasons JavaScript is so popular is because it is very easy to implement. All you need to do is put your code in the HTML document and tell the browser that it is JavaScript. Another reason developers love JavaScript is because it works on web users’ computers — even when they are offline!

JavaScript allows you to create highly responsive interfaces that improve the user experience and provide dynamic functionality, without having to wait for the server to react and show another page.

JavaScript is the grandfather of programming languages, but it doesn’t mean for a second that it’s outdated or out-of- fashion, because JavaScript is an important part of the future. Several front-end frameworks for JavaScript such as React and AngularJS have huge future potential as IoT and mobile devices become more popular.

One of the most recent uses of JavaScript is related to Artificial Intelligence (Machine learning), and we all know by now that AI is a big part of the future, so we doubt we’ll see JavaScript drop in popularity anytime soon.

Oh! And let’s not forget one of the main reasons a developer chooses to learn a new programming language: the salary!

In Europe, the average salary of a JavaScript developer oscillates between €42,807/year and €59,479/year (depending on seniority), according to PayScale.


Python grew in popularity in the last year, because it is used in scientific computing, data mining and machine learning. This is the number 1 reason you should learn Python this year: machine learning and data mining are trending in the IT industry.

This programming language is used by NASA and Google. The creator of Python, Guido van Rossum worked at Google for 8 years.

Python is simple and readable and is one of the high-level programming languages widely used for general-purpose programs.

In Europe, the average salary of a Python developer is between €45,413/year - €60,298/year (depending on seniority), according to PayScale.


Java is not as popular as it used to be in 2017, but it’s still one of the main programming languages that you should learn. Java is 20 years old and it’s used by millions of developers and billions of devices worldwide, and is able to run on any hardware and operating system through the Java Virtual Machine, which makes it cross-platform compatible.

The value of Java is captured by its slogan: “Write once, run anywhere”. 90% of Fortune 500 companies use Java as a server-side language for backend development.

If all of the above doesn’t convince you, then know this: Java is the basis for the Android operating system and the most common language for developing Android apps.

Java is one of the common programming languages that developers have to learn from the beginning of their career because it’s flexible and modular with entrenched business application and job opportunities.

In Europe, the average salary of a Java developer is between €30,092/year - €61,056/year (depending on seniority), according to PayScale.


C#(pronounced C Sharp)is an object-oriented programming language designed by Microsoft to run on .NET platform. C# is a multi paradigm programming language recommended for developing games so, if you are an aspiring video game developer you must learn C#.

If you’re coming from another language in the C family, C# will definitely be easy to learn. C# 7.2 added some new features to avoid unnecessary copying.

C# is a programming language that will not go out of fashion soon, because it’s used for building 3D and 2D video games, using the popular Unity game engine.

In Europe, the average salary of a C# developer is between $35,000/year and $80,000/year (depending on seniority), according to PayScale.


SWIFT was built by Apple and is a more popular successor of Objective-C. SWIFT is a clean, fast and error-free programming language, that will save you time and energy by reducing the length of the code.

SWIFT is a relatively new language and the 13th most popular language by pull request, according to Github's State of the Octoverse Report. SWIFT is used to develop iOS and macOS applications.

One of the advantages of SWIFT is that is open source and it can be used on Linux or Window system if compliers and apps are all compatible with Apple devices.

Learning SWIFT is a wise investment for software developers because iOS runs on every iPhone, iPad, watchOS or tvOS in the world.,

In Europe, the average salary for an SWIFT developer is between €33,421/year - €65,604/year (depending on seniority), according to PayScale.


If you are an aspiring Android developer, then you have to learn KOTLIN! This programming language received official support from Google and Android Studio (Google declared KOTLIN an official language for Android) and it appears that will be in high demand in the foreseeable future.

KOTLIN is concise, safe, interoperable and tool-friendly. KOTLIN relaxes Java's restriction of only allowing static methods and variables inside a class body. Static objects and functions can be defined at the top level of the package without needing a redundant class level.

You may ask yourself if it’s necessary to learn KOTLIN if you already know Java, and the answer is: YES!

Why? Because in JAVA there are 86 lines of code and in KOTLIN there is only 1 line of code that does the same work. That is a pretty good argument to start learning KOTLIN right now!

In Europe, the average salary of a KOTLIN developer is an average of £65,000, according to IT Jobs Watch.


R is an environment used for statistics, graphic representation and data analysis. This programming language is the no. 1 choice for data scientists, so it’s a stable and profitable career option.

R is open-source and it can be used in software environment for both statistical computing and graphics and, in 2018, R was the “least-disliked” language, according to a Stack Overflow survey.

Another reason for you to learn R in 2018 is the fact that this programming language compiles and runs on a wide variety of UNIX platforms, Windows and MacOS.

R is freely available under the GNU (General Public License), and pre-compiled binary versions are provided for various operating systems.

In Europe, the average salary of an R developer is £60,000, according to IT Jobs Watch.


Although it hasn’t been around for too long, Typescript is very popular among frontend developers because it behaves just like JavaScript, but with some extra features.

Developed by Microsoft, TypeScript is a superset of JavaScript which compiles into JavaScript code and it’s used to improve your code quality with OOP features and static typing.

TypeScript has its own syntax for handling type annotations and this allows TS developers to specify the types of variables, parameters, and callbacks.

The syntaxes of Typescript are similar with the ones of C#, because both programming languages were created by the same person - Anders Hejlsberg, a prominent Danish software engineer who co-designed several popular and commercially successful programming languages and development tools.

A very good reason for you to start learning Typescript is the fact that it is the primary language used in Angular Documentation.

In Europe, the average salary of a Typescript developer is around £50,000/year, depending on seniority.


Released in 2001, D is an object-oriented, imperative, multi-paradigm system programming language created by Walter Bright of Digital Mars,who was joined in 2007 by the Romanian developer Andrei Alexandrescu.

The D programming language was considered a re-engineered C++, but it’s actually a distinct language that was also inspired from Java, Python, Ruby, C#, and Eiffel.

D harmoniously integrates several programming paradigms, such as functional style, imperative, object oriented, metaprogramming, and concurrent (actor model).

This programming language has a feature that is useful for designing algorithms without tying them to specific types. With D, developers can do more in less time by writing generic and reusable code, using templates.

D is not very popular yet, but you should keep an eye out for this programming language, because it has all the qualities to become very useful in the near future.


Before you start learning a new programming language, make sure it’s a sought language that will help you gain more money and open more doors for you. And make sure you like it, because it’s much easier to learn a programming language you like.
