Js2Ts

What is Js2Ts?

Js2Ts is a tool that uses AI to convert JavaScript code into TypeScript. Paste your JavaScript code into the input area, click “Convert,” and the TypeScript version appears in the output box, ready to copy. You can clear the fields at any time to convert new code. The tool was developed by Yuval Suede.

What is Js2Ts used for?

• Converting JavaScript to TypeScript: Handles the translation directly.
• Automating the process: Eliminates manual conversion work.
• Streamlining migrations: Makes moving JavaScript projects to TypeScript smoother.
• Adopting TypeScript benefits: Helps you start using static typing and improved code safety.

Example

This JavaScript:

function greet(name) {
 return 'Hello, ' + name + '!';
}

console.log(greet('Alice')); // Output: Hello, Alice!

is converted to TypeScript as:

function greet(name: string): string {
 return 'Hello, ' + name + '!';
}

console.log(greet('Alice')); // Output: Hello, Alice!

Js2Ts is useful for web developers, software engineers, and programmers — anyone working with JavaScript who wants to transition to or use TypeScript.
