TypeScript is a programming language developed by Microsoft and considered as a super-set of JavaScript. It includes advanced features such as static typing, classes and interfaces that are not present in JavaScript, which makes your code more understandable and maintainable in larger and more complex projects. TypeScript code is compiled to JavaScript and outputs executable JavaScript code, making it compatible with modern browsers or JavaScript runtimes.
TypeScript is supported by popular JavaScript frameworks and libraries such as AngularJS. It is also supported by popular development environments like Visual Studio Code, WebStorm, and others, making it easy and efficient to use.
TypeScript also supports many popular libraries and frameworks that are widely used in JavaScript, such as React, Vue.js, Node.js, and many more. This allows your TypeScript code to be compatible with other code and makes it more flexible.
