What is JSON?

The most popular type of data format in APIs and web applications is JSON (JavaScript Object Notation). It is light and easy to read and it is ideal in the transmission of data between the client and server.

However, as projects scale, it is dangerous to use untyped JSON and this is where TypeScript comes in.

Why is TypeScript the future?

TypeScript is a superset of JavaScript, which introduces static typing to your codebase, making it stronger, scalable, and bug-free.

Benefits of using TypeScript:

• Avoids the type-related bugs
• Makes the code easier to read
• Allows superior auto-complete and IntelliSense
• Makes code refactoring easy

Converting JSON to TypeScript automatically  interfaces lets us guarantee type safety, minimize mistakes, and enhance work in big codebases.

About the JS2TS tool

The JS2TS tool is a web-based JSON-to-TypeScript interface converter that converts JSON to TypeScript data to clean, ready-to-use instantly.

It was made to ease your work process through automation of the routine tasks and allow you to:
