Most Popular Programming Languages

There are numerous programming languages some are called lower level languages and some high-level languages. But that doesn’t mean that one language is better than other languages. Every language has its own use and benefits and a lot of features. When we talk about a developer, we have different domains like an Android developer, it can be an IOS developer, it can be an embedded developer like IOT, you can get into machine learning, you can be an enterprise developer.

So based on what market you are working on you can choose a particular language there. For example, if you want to be into mobile app development, we have two options to choose from. You can either go for android or for IOS. For Android, the official language which we use is Java or you can say the Java is the dominant language for android applications but we also have Kotlin that we can use for the same purpose. The only problem with Java is, it is very verbose. You has to mention everything.

That’s not the case with Kotlin. It is short and simple. But then if you know Java, you can learn Kotlin very easily. And then for IOS, we have a language that is swift. Swift is the official language for IOS from Apple. And if you want to be an IOS developer, swift is the best option. But then what if you want to use one language for both purposes. And that’s where we have JavaScript. JavaScript is evolving like anything and now it can be used everywhere.

It can be used on various platforms. JavaScript can be used for building an app for mobile and it can also be used for web development. We can also create a database that is MongoDB with JavaScript.  You can almost use JavaScript for the entire stack. Technology is constantly going through an evolution, so are the languages that are used to develop them. There are so many languages today that a beginner will find himself lost when deciding what to learn.

Popular Programming Languages 

Let’s have a look at some of the popular programming languages of 2019. We will start with the most popular one first.

This is an object-oriented block-structured programming language. It provides features like better readability, speed, and dynamic libraries. These features ensure lesser errors, reduced application size, and improved performance. Swift is specifically developed for application development. Apple switched to Swift from objective C++ hence, it is influencing the Mac OS, Watch OS and apple app development which are its major highlights. Swift has two major frameworks namely Cocoa, and Cocoa Touch which are centered around application development. With application development at its core companies like Apple, Walmart, Amazon, and google summing to its popularity and demand.


Developed by tech-giant Google itself, GoLang with features like concurrency which is hard to find in other languages. Google’s versatility as a company is reflected in the language they developed too and can be used in a bunch of different scenarios, be it, machine learning or web development. But its highlight is definitely system development due to Golang scope of high scalability. Golang got popular in recent times. It has some really useful frameworks such as Revel and Beego. Golang developers are in high demand and low supply which make 2019 a good time to learn Golang and added to your resume so that you can apply to companies like CISCO, Tech system, etc.

C#(C Sharp):

C# (pronounced C sharp) is a programming language with a rich set of libraries. Which makes the compilation and execution of C sharp lightning fast.

Also, it is used alongside languages such as ESP and web development. C sharp is an important part of virtual reality games and is popularly known for developing Windows 8 and Windows 10 applications. It is also used along with the Unity 3D game engine for game development. C sharp uses frameworks like Xamarin, and .NET for building mobile applications and game development.


C++ is a simple yet powerful programming language that provides a structural approach. It is one of the most popular languages from which developers usually start their programming journey. It is an object-oriented language that is rich with a set of library functions and data types. Using C++ you can develop the most reliable software. Major domains in which C++ is used mostly are game development, scripting, mobile applications, and web solutions. C++ provides a generic framework and libraries like WX-Widgets, GTK++, Boost, Qt, etc. major highlights of C++ applications are like Adobe Photoshop, Google Chromium, MapReduce, Mozilla Firefox, MySQL database, and operating systems from Apple and Microsoft are also developed using C++.


R is a programming language that has been universally accepted as a language for a data scientist. R is the most popular programming language for statistical analysis and data science.
