Thus, we decided to guide you into the most popular programming languages in 2020 and help you make such a vital choice when you just start your project. 

How to Choose the First Programming Language to Learn? 

Usually, the choice of a programming language depends on a specific need (website development, software development, mobile app development etc). But if you are a beginner and you don’t understand this undiscovered IT world, you can rely on the following criteria when choosing the programming language in your tech stack:


  • Learning Curve. It can be rather discouraging when you start learning the programming language and get stuck at once. Yes, when you are a newbie, it’s quite common for you to l face challenges. But anyway, you can make your life easier and pick a simpler language to start. For instance, it can be JavaScript, CSS or Python, which can help you to pave the way into your IT career. 



  • Market Demand. Demanded language is a key to your successful career and various interesting projects. It is a good idea to browse sites with job vacancies and ratings of programming languages. Thus, you can see how many specialists are there on the market and choose the technologies that are easier to work with. 



  • Your Own Preferences. Ideally, you have to enjoy your job so it’s essential to pick the programming language you like to work with, but you don’t need to focus on a single language. You can choose several languages and learn the basics – it won’t take a lot of time, but you can compare these languages and understand what’s comfortable for you to work with. 


Python. Hero of the Year or the Pick You Can’t Go Wrong With 

According to the PYPL Index, Python is the most popular programming language worldwide in 2020 (31,73%). It evolved over the last 5 years and got ahead of Java (17,13%) and JavaScript (7,98%). This index is calculated by analyzing how often people search language tutorials on Google. 

Python is perfect for beginners – it has quite a simple, well-structured code and inbuilt solutions for many basic tasks. Thanks to its simplicity and highly active community, you can learn to write code fast and painless. Python is the language for general purposes and can be used to create almost anything. It’s free, flexible, open-source and demanded.

  • Machine Learning
  • Back-end Development

There are a lot of vacancies mentioning Python. But sometimes you’ll need to complement your tech stack with other technologies as Python is frequently used as an additional language. In such cases it works only as a bonus so it’s not enough to know only Python to fit all the requirements. However, these cases are very rare, since a lot of projects require Python as their primary language, and it is still a perfect variant to start your IT career.  

Down the Programming Rabbit Hole

Apart from  Python, there are other popular and demanded programming languages, suitable for various fields and tasks. Here are 2 more options for you to choose from. 


Java has been one of the most popular programming languages worldwide since 1995. It’s also used for a variety of tasks including Android app development, commercial software apps etc. Java is primarily used as a  back-end technology, so if you want to create web apps or develop the server-side of the website, you should consider choosing Java.

If the back-end languages always compete with each other, in the front-end everything is easier – JavaScript is the main programming language here and there are always a lot of vacancies requiring it. So if you are looking for a skilled front-end developer or want to learn it yourself, JavaScript is the best match for you
