Every software or IT industry has professional programmers who are responsible to run their product smoothly. A Programming language is the most essential tool for software developers to write code and that is the reason every year it’s a confusing question among developers and newbie programmers which language they should pick up to learn. There are dozens of programming languages so picking the ideal one for a job can be quite a tricky decision. You need to consider so many factors such as learning curve, stability, jobs in the market, salary, community help, and a lot of things before choosing a programming language. 


We have compared some popular programming languages in the world on google trends and let’s see what the latest information it gives to us about popular programming languages in 2019. 

Top 10 Programming Language - Google Trends


Top 10 Programming Language - Google Trends

Every year the largest online developer community stackoverflow also conduct their own survey about the most popular programming languages. Last year Python and Javascript were on the top. This year we are expecting a slight difference among the ranking of these programming languages. Based on different categories of developers, different kinds of applications, job demands, google trend reports, learning curve, salaries we are going to list out the top 10 programming languages to learn in 2020. 

1. Python

If we talk about easy-to-read, easy-to-learn, and easy-to-use language then nothing can beat Python and that makes Python an excellent choice for beginners. Python is now being introduced as the very first language in the majority of universities all over the globe. Django, Flask, Pyramid these all python frameworks are popular among developers. Python syntax is user-friendly in comparison to other languages and that increases developers’ productivity eventually. These all are the reason it is one of the most preferred languages among programmers. 

  • Open source and object oriented.
  • Can be integrated with C and C++.
  • Cross browser support.
  • Career in various field such as Scripting, Web Development, Machine Learning, Deep Learning, Data Science, Artificial Intelligence, Robotics, and Big Data.
  • 1M+ repositories on Github.
  • Companies working on Python: Google, Facebook, Instagram, Spotify, Paytm, Netflix, Quora.

2. JavaScript

Last year javascript was on the top in the StackOverflow survey report and this year it will be also one of the most popular languages among developers. Android, iOS, or the desktop javascript is almost everywhere and it will definitely increase it’s spread this year as well. Javascript is providing ultimate business solutions and that is the reason it is on the top of the list for a tech startup and for tech giant companies as well. If you are looking for a job quickly and easily then javascript opens a lot of opportunities for you in the job market. Javascript is now used for both frontend and backend side. There are so many frameworks and libraries available for javascript that are quite popular among web developers such as Angular, React, Vue, Meteor, and a lot more.

3. Java

Whether you are in the programming field or not you must have definitely heard about this popular programming language. The reason why this is on the top of the list is that there are so many large organizations still work on this language. Java is widely used in android app development and for building enterprise-scale web applications. Google has also created an excellent Java-based Android development framework – Android Studio. There was a little bit decline in the popularity of java but Spring Boot (framework of java) is getting enormous popularity these days because of some of the refinement in the frameworks done recently. The recent update in this framework made it fantastic and probably, it will boost up in the future as well. If you are looking forward to learning java then going with spring boot won’t be a wrong choice for you. 

  • Open source, Object-Oriented language.
  • Cross-platform compatible.
  • Stability, Strong memory management, and automatic garbage collection.
  • High performance, top-notch security.
  • Platform independent because of JVM feature.
  • 1M+ repositories on Github.
  • Companies working on Java: HCL, Adobe, Intuit, Qualcomm, Flipkart, Amazon.

4. C and C++

Surely python and javascript are easy to learn and easy to use language for most of the applications but when it comes to choosing the fastest language then C and C++ is the best choice. A lot of low-level stuff such as operating systems, file systems, embedded systems, kernel development can be built using C or C++. Almost all the modern and popular languages today inherit the properties of C and C++. C++ is still used in Microsoft Windows and Google projects. Apple also uses C++ language to develop its iOS operating system. Most of competitive programmers still prefer to use C++ because it is extremely fast and stable. 

  • C++ is an object-oriented programming language.
  • Availability of ready-to-use STL libraries in C++.
  • Used in Game development, GUI applications, Desktop applications, real-time mathematical simulations.
  • 7M+ repositories for C and 560K+ repositories for C++ on Github
  • Companies working on C and C++: eBay, Spotify, Adobe, Oracle, HP, Huawei, IBM, PhonePe

5. Golang

The language is developed by Google and it is also a simple language like Python so people who love to work on Python, they will definitely love this language as well. This language is pretty much already popular and scaling quite a lot at the backend services. In 2019 this language didn’t get much popularity but in 2020 it will be rising quite a lot. Go language is more efficient than C++ and it provides features to write concurrent programs that are difficult in other programming languages. Revel, Beego, Martini, Gin all are popular frameworks of this language. Its popularity is mostly in Silicon Valley startups but it is spreading all over the world day by day.
