TypeScript
TypeScript is a programming language that is a super set of JavaScript. It adds optional static typing and other features to the language, making it more suitable for large-scale, complex projects. TypeScript allows developers to catch errors early in the development process, by catching type errors before the code is even run. This can greatly reduce the number of bugs and make the development process more efficient. It also provides features such as classes, interfaces, and modules, which are not available in JavaScript.
It was developed and is maintained by Microsoft and is widely used in web development, mainly in Angular projects. TypeScript code can be transpiled to JavaScript, so it can be run in any JavaScript environment.
