 In this article, we will see the difference between JavaScript and TypeScript. These are the 2 most widely used scripting languages.

JavaScript

• JavaScript is a scripting language with first-class functions to create dynamic web pages.
• JavaScript is loosely typed. In JavaScript, only dynamic typing is supported, but not static typing.
• JavaScript is a simple language that optimizes code for compatibility, easy to read and write.
• JavaScript does not need a compilation.
• JavaScript is only a scripting language that gives functionality to the pages. There is no support for interfaces.
• JavaScript does not require annotation.
• JavaScript does not have a feature for prototyping.
• In JavaScript, errors are detected only at the run time, since it is an interpreted language.
• JavaScript is ideally used for web applications, mobile and desktop applications, and game development.
• JavaScript runs directly on the browser and supports cross-platform, cross browsers.

TypeScript

• TypeScript is a powerful object-oriented language as a superset to JavaScript, with generic and JS features to overcome the complexities of JS.
• TypeScript is strongly typed. TypeScript supports both static and dynamic typing.
• TypeScript is a powerful object-oriented language as a superset to JavaScript, with generic and JS features to overcome the complexities of JS.
• TypeScript is strongly typed. TypeScript supports both static and dynamic typing.
• TypeScript requires the need for annotation to get the full advantage of TypeScript features.
• The prototyping feature is available in TypeScript language.
• Errors are detected or highlighted in the early development stage in TypeScript.
• TypeScript is a more front-end-oriented language with rich IDE support. It is best suited for complex applications and also any JS applications as well.
