TypeScript

TypeScript is a programming language that is a superset of JavaScript. It was developed by Microsoft and first released in 2012. It extends JavaScript by adding static typing and other features such as classes, interfaces, and modules.

The main goal of TypeScript is to make it easier to develop and maintain large-scale JavaScript applications. By adding type annotations, TypeScript helps catch errors early in the development process, improving code quality and reducing the number of bugs that make it into production.

TypeScript code is compiled into plain JavaScript, which can be run in any modern web browser or Node.js environment. TypeScript is also supported by many popular code editors, including Visual Studio Code, which provides features such as code completion, refactoring, and error checking.

This JavaScript with syntax for types is increasingly popular among web developers, especially in large-scale projects, due to its ability to provide better code quality, maintainability, and scalability.
