What is .ts file?

The TS file stands for TypeScript file. It is a text-based format for describing the structure of a program written in TypeScript. TypeScript is a programming language that is a superset of JavaScript and provides additional features like type checking, class support, and interfaces.

The .ts files contain TypeScript code and are compiled into JavaScript code, which can then be run on any browser or platform. TypeScript makes it easier to build and maintain large-scale JavaScript applications, as it provides a more structured and scalable approach to development.

Typically, a TypeScript project will have multiple .ts files that are linked together through their imports and exports. The compiler will then bundle these files into a single JavaScript file that can be deployed to a web server or included in an HTML file.

To work with .ts files, developers need to have a TypeScript compiler installed on their computer. Most modern IDEs like Visual Studio Code and WebStorm have built-in support for TypeScript and can automatically compile the code as it is being written.
