According to Stack overflow survey, Ruby is loved by 42.9% of developers.
Ruby is straitforward and easy to learn.
Unlike other programming languages and frameworks, Ruby on Rails does not need complex configurations that add little value to the main application. This saves developers from writing large pieces of complex code.
Airbnb, Bloomberg, Dribbble.com, GitHub and many more are using Ruby on Rails
According to GitHub, there are more then 132K active repositories using Ruby.
C++ is a general-purpose programming language created by Bjarne Stroustrup as an extension of the C programming language. C++ is now the fastest-growing programming language in terms of popularity.
Generally C++ is used in operating systems because of the speed and strongly typed nature. C++ is closer to the hardware level and is a low-level language. That is why, it is used in many compilers as a backend language.
C++ is soo strong, that many popular data base are written in C++ such as MongoDB, MySQL, MemSQL, etc.,
As its an old language, it’s having a large online community support. According to a survey on Stack overflow C++ is liked by over 43% of developers. It does not depend on anything or any other language you can learn it directly.
For a beginner it might be a bit tough to understand it’s concept and syntax, but once you get familiar, you’ll definetly love C++. It is also used in game development as well, mostly used with Unreal Gaming Engine.
I personally love C++, as it is fast and way too power full language, we can build any thing using C++ from console application to High quality graphics game. If you love to build console application and or love video games, and want to start your career in game developement, I highly recommend go with C++ and Unreal engine .
Learning C++ by a book which is published in 90’s will not give much of it. There are a lot of updates and new feactures in C++ 11 and further, C++ 17 has soo many features about memory mangement and more.
According to GitHub, there are more then 86K active repositories using C++ programming language.
We can’t complete the top 10 list without mentioning the PHP. It is one of the most famous and widely used server side language, used in web development.
PHP is a popular general-purpose scripting language that is especially suited to web development.
Fast, flexible and pragmatic, PHP powers everything from your blog to the most popular websites in the world.
PHP is a domaniting language. In developing conturies it’s a tool to many people to do their business. PHP has a lot of open source tools, one of them is Word Press. It is most widely used in developing small business websites and blogs websites, as it is easy to use.

PHP has a wide range of open source web frameworks such as Laravel, Symfony, Codelgniter, Magento and many more. In a survey conducted by Stack overflow over 33.7% of PHP users loved it.
Just learning PHP won’t help much, as raw PHP is not that much used now a days in the Industry. I highly recommend to learn atleast a framework of PHP. My recommendation Laravel, as it is getting popular and is widely used, and comes with almost every thing we need to build a full fledge web application.
PHP is soo easy to start with, even a beginner can easily understand the syntax
PHP has a greate documentation, easy to understand
According to GitHub, there are more then 138K active repositories using PHP language.
Swift is a general-purpose, multi-paradigm, compiled programming language developed by Apple Inc. and the open-source community, first released in 2014.
Swift is a powerful and intuitive programming language for macOS, iOS, watchOS, tvOS and beyond. Writing Swift code is interactive and fun, the syntax is concise yet expressive, and Swift includes modern features developers love. Swift code is safe by design, yet also produces software that runs lightning-fast.
Swift is a fantastic way to write software, whether it’s for phones, desktops, servers, or anything else that runs code. It’s a safe, fast, and interactive programming language that combines the best in modern language thinking with wisdom from the wider Apple engineering culture and the diverse contributions from its open-source community.
Swift eliminates entire classes of unsafe code. Variables are always initialized before use, arrays and integers are checked for overflow, memory is automatically managed, and enforcement of exclusive access to memory guards against many programming mistakes.
Swift can open doors to the world of coding. In fact, it was designed to be anyone’s first programming language, whether you’re still in school or exploring new career paths.
The only drawback to learn Swift is, you need to have an Apple device to run XCode to compile Swift. There are some online tools available to compile swift code, but we cannot build an entire application using these online tools.
According to GitHub, there are more than 11K repositories available of Swift.
At position 3, I would like to put Java, of course there are some issues in liciencing, in last couple of years. But Java is soo much deep in IT industry. Yeah Java do have a bit wierd and a bit long syntax to work on but, it is worth it.
Again just learning java isn’t giving much, I highly recommend to learn at least one of it’s framework.
Java is also widely used in Android mobile application developement, Java has an enormous online community, for all of it’s framework. 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.
Java application are platfrom independent because of JVM
It has high security and top performance
According to GitHub, there are more than 222K repositories available using Java.
Picking the languages for second position was not that hard. Python is an interpreted, high-level and general-purpose programming language. Python’s design philosophy emphasizes code readability with its notable use of significant whitespace.
Python is an excellent choice for the beginner to learn as their first programming language, because of its easy syntax. Python is widely used programming language.
You can build almost everything by just python, from desktop application to web application and even games. Mobile application development in python is not that popular nowadays, but yes we can build mobile application as well using Python.
Python is also famous for analyist, data science and machine learning as well. Python has a whole lot of libraries to work on Data Science and Machine learning. In a Stack overflow survey 66.7% users loved working on python.
There are also some famous web development framework built on top of Python Django, Flask etc.,
Learning Python alone will not help you much, it is recommended to learn atleast one of it’s framework, my recommendation is Django.
According to Github there are more than 1M GitHub repositories.
It has a large community support
Some Honorable Mention
Rust is a multi-paradigm programming language designed for performance and safety, especially safe concurrency. Rust is syntactically similar to C++, but can guarantee memory safety by using a borrow checker to validate references.
Rust is blazingly fast and memory-efficient: with no runtime or garbage collector, it can power performance-critical services, run on embedded devices, and easily integrate with other languages.
Rust has great documentation, a friendly compiler with useful error messages, and top-notch tooling
Rust is getting famous among developers. Here is the indepth Stack overflow link of why its getting famous.
According to a survey on Stack overflow Rust is most loved languages by the developers, over 86% of users loved working on Rust
Types provide a way to describe the shape of an object, providing better documentation, and allowing TypeScript to validate that your code is working correctly.
TypeScript is strictly typed language, where we need to define the type of the data which we are using in the variable that allow us to validate our code better.
TypeScript is also getting famous with time, now we also use TypeScript to create Node.js applications as well. In the upcomming years it will shine like a start.
Dart is a client-optimized programming language for apps on multiple platforms. It is developed by Google and is used to build mobile, desktop, server, and web applications.
Dart is created by Google, initialy for Angular. But their plan got faild and it didn’t worked well with Angular, So they have to change their plan to use TypeScript instead with Angular.
Now Google has come with a new idea of using Dart with one of it’s mobile application framework called Flutter. Flutter create native, 2D , materilized UI mobile application both for IOS and Android.
And recently it is getting used by many companies. As Flutter is built on top of Dart, it is worth mentioning.
Go is a statically typed, compiled programming language designed at Google. Go is syntactically similar to C, but with memory safety, garbage collection, structural typing, and CSP-style concurrency.
It is an open source programming language that makes it easy to build simple, reliable, and efficient software. This language is pretty much already popular and scaling quite a lot at the backend services. Go language is more efficient than C++ and it provides features to write concurrent programs that are difficult in other programming languages.
It gives excellent support for multithreading.
Ideal for building SPAs (single-page applications).
GO can also be used in Distributed system, Big data, Cloud Computing and for other large scale or complex applications.
Thank you. Happy coding! 😉
