TypeScript is getting more popular in Full-stack development. In terms of popularity, in the last two years TypeScript pulled ahead of Ruby, Shell, and C. In the latest State of Octoverse report, which tracks programming language popularity over time, TypeScript ranks seventh.

Why TypeScript

When JavaScript was developed then JavaScript development team introduced JavaScript as a client-side programming language. But when people were using JavaScript then developer get to know that JavaScript can be used as a server-side programming language also. But When JavaScript was growing then the code of JavaScript became complex and heavy. Because of this, JavaScript was even not able to full fill the requirement of Object-oriented programming language. This prevents JavaScript from succeeding at the enterprise level as a server-side technology. Then TypeScript was developed by the development team to bridge this gap.


Overview

TypeScript is an open-source pure object-oriented programming language. It is a strongly typed superset of JavaScript which compiles to plain JavaScript. It contains all elements of the JavaScript. It is a language designed for large-scale JavaScript application development, which can be executed on any browser, any Host, and any Operating System. The TypeScript is a language as well as a set of tools. TypeScript is the ES6 version of JavaScript with some additional features.

TypeScript cannot run directly on the browser. It needs a compiler to compile the file and generate it in JavaScript file, which can run directly on the browser. The TypeScript source file is in “.ts” extension. We can use any valid “.js” file by renaming it to “.ts” file. TypeScript uses TSC (TypeScript Compiler) compiler, which convert TypeScript code (.ts file) to JavaScript (.js file).

A Look Into How Languages Are Written in Their Own Language

It may come as a surprise to learn that C is largely written in C, that Java is written in Java, and that Typescript is written in… Typescript! To many, this seems like a technological version of the “which came first, the chicken or the egg?” question. This sure seems like a contradiction — if C is written in C, doesn’t C have to already exist?
