TypeScript to JavaScript Converter
 

Our TypeScript to JavaScript converter strips type annotations and TypeScript-specific syntax
          from your code, producing clean JavaScript that runs in any environment. Perfect for sharing
          code with non-TypeScript projects or understanding what TypeScript compiles to.

 
What is TypeScript?
 

TypeScript is a strongly-typed superset of JavaScript that adds optional static typing,
          interfaces, and other features. When TypeScript is compiled, the type information is
          removed, leaving plain JavaScript that browsers and Node.js can execute.

 
How It Works
 

This tool uses pattern matching to identify and remove TypeScript-specific syntax:
