Post for all Platform

GitHub is a Git repository hosting service that offers a Web-based graphical interface. It helps its 40 million users across the globe to build software. ( Being a massive code repository, GitHub has information about everything that’s happening in the world of technology. It is difficult to find the most suited programming language as per your necessities as there are many programming languages available. To help you out in this situation, we have made a list of programming languages that are going into 2020 according to GitHub.

  1. Python

GitHub determined the popularity of different programming languages based on Google search

results. Python was searched the most among all other programming languages. According to the report, 29.9 percent of the tutorials were searched for Python while Java had 19.1 % and JavaScript had 8.2 %. (

Python is one of the key programming languages across the globe. It was first implemented in the 1980s and it can be used to develop desktop apps, machine learnings, robotics, Artificial Intelligence, Web applications, and network servers. Frameworks like Django, Turbo Gear, and Pyramids are based on Python and that’s not all. This language has been used to create popular video games like Civilization IV as well.

Python had been updated three times with its last update- Python3- finishing in 2008. Python has been used by large companies like Google, Instagram, and Dropbox for a long time.

  • It is slower than natively compiled programming languages like C and C++.
  1. JavaScript

A client-side scripting language, JavaScript, is used to enhance the interaction of a user with the webpage. This objective-oriented computer programming language has a syntax that resembles the programming language C. Although they sound similar, JavaScript and Java are not related. While Java is a very complex programming language, JavaScript is only a scripting language. JavaScript is used for a diverse range of applications. It is an interpreted language. Popular websites like YouTube, Facebook, Google, Wikipedia, and Amazon are some examples.  A superset of JavaScript, Typescript can be used to add optional static typing features to the language software.

  • The quality of PHP frameworks can differ from time to time. It is very inconvenient considering how much it relies on PHP frameworks.
  1. C/C++

A procedural programming language developed as a system programming language to write an operating system. It is generally used to build desktop applications and is considered to be the base of all programming languages. Programming languages like Java, PHP, JavaScript, etc. are mainly based on C language. C++ is nearly a superset of C language.

Low-level access to memory, a simple set of keywords, and a clean style are some of its notable features.

  1. Swift- 

Swift has replaced Objective-C with its simplicity, ease, and updates. It was introduced in 2014 by Apple at the annual Worldwide Developers Conference. Within 3 years, that is, in 2017, it has seen massive growth. It is used to develop iOS applications but being open-source, applications written in Swift can be exported to Android and Windows. Dependency mirroring, target-specific build settings, customized deployment targets, and the ability to generate code coverage data are some notable Swift 5 features. It can be used with the IBM Swift Sandbox and the IBM Bluemix. Many popular iOS apps are built with Swift. Mozilla Firefox, WordPress and SoundCloud are some names in that list.

Advantages of Swift:

  • Its close resemblance to English makes it easier for programmers to learn and use.
  • Swift library offers string reimplementation with UTF-8.
  • Very fast as compared to other popular programming languages, such as Objective-C and Python.
  • Easier to share code with both frontend and backend development.
  • Module Stability has made it possible for a Swift 5 library to work with a future Swift compiler.
  • Swift 5 defaults to allow exclusive access to memory for Debug as well as Release builds.
  • Its support for callable type significantly improves interoperability with languages like Python, JavaScript, and Ruby.
  • The Swift run command can also import libraries in the REPL without building an executable.
  • Uses modern programming conventions.

Disadvantages of Swift:

  • Altercations and adjustments in each update tend to make it unstable.
  • Interoperability with third-party tools are not enough which makes functionality and connectivity with third-party frameworks difficult.
  • Limited community support.
  • It can be used only for iOS7 or later apps.

  1. TypeScript-

TypeScript is JavaScript for application scale development. It is an open-source language that is created and maintained by Microsoft. It is a JavaScript superset and often called modern JavaScript. It has a static type system. Being a compiled language, its default compilation target is JavaScript.

Advantages of TypeScript:

  • An object-oriented programming language.
  • Types help with code management.
  • Seamless integration of declaration files makes JavaScript frameworks and libraries accessible.
  • Helps the programmers with type checking.

Disadvantages of TypeScript:

  • Very complicated typing system.
  • Requires compilation.
  • It provides a false sense of security as programmers tend to heavily rely on the ability to check types.

As we have seen, programmers can use various programming languages as per their needs. Based on the information provided by GitHub, a programmer can make an informed decision. It is necessary to weigh in the advantages and disadvantages of these programming languages. As per the recent trends, these ten programming languages will be used in 2020. Understand and analyze the project requirements and select the programming language accordingly. For more info:
