# TypeScript First

> Everything is developed with type-safety in mind, so we strongly recommend you also use TypeScript to reap the benefits.

Overlayed is built TypeScript-first, so you'll get full type-safety and intellisense when using it.

If you've never used it and it seems daunting, we promise it's worth it. Here's the
[docs](https://www.typescriptlang.org/docs/handbook/typescript-in-5-minutes.html) to get you started.

<Tip>Make sure to enable `moduleResolution: "bundler"` in your tsconfig.json to ensure intellisense works properly</Tip>

## Using JavaScript

Rest assured, if you prefer to use JavaScript, you can do so with no extra changes.
