Scalablytyped

Scalablytyped is a software library that aims to provide type safety for JavaScript applications by enabling developers to use TypeScript definitions from NPM within their JavaScript code. It acts as a bridge, allowing JavaScript projects to leverage the benefits of type checking without requiring a full migration to TypeScript. The core functionality involves generating typed JavaScript code from existing TypeScript declaration files. This process typically involves a build step where Scalablytyped analyzes the `.d.ts` files and produces corresponding JavaScript files that include type annotations and runtime type checks. This allows JavaScript developers to receive type information in their IDEs, such as autocompletion and error highlighting, even when consuming libraries that are primarily written in or typed for TypeScript. Scalablytyped aims to reduce the friction of integrating typed libraries into JavaScript codebases, offering a way to gradually adopt type safety. It's particularly useful for projects that want to benefit from the vast ecosystem of typed libraries available on NPM but are not ready or willing to adopt TypeScript as their primary development language. The library handles the complexities of type system translation, making it easier for JavaScript developers to work with typed dependencies.
