# Usage with JavaScript

## Is it possible to use Mantine with JavaScript?

Yes, it's possible to use all `@mantine/*` packages (as well as all other npm packages) with JavaScript.
`@mantine/*` packages are written in TypeScript and have type definitions, so you'll get some benefits
of TypeScript (like autocompletion in your IDE) when using them with JavaScript.

## Transforming demos code to JavaScript

All demos in Mantine documentation are written in TypeScript. In most cases, there's no difference between
TypeScript and JavaScript code – you don't have to do anything.

To transform TypeScript code to JavaScript, you can use the [TypeScript playground](https://www.typescriptlang.org/play?jsx=1\&preserveValueImports=false#code/Q)
– paste the demo code into the playground and all types will be removed. Note that you'll also need
to remove type imports from the code.

Example of transformed code:

```tsx
// TypeScript code
import { Button, ButtonProps } from '@mantine/core';

interface MyButtonProps extends ButtonProps {
  myProp: string;
}

function MyButton({ myProp, ...others }: MyButtonProps) {
  return <Button {...others} />;
}
```

```tsx
// JavaScript code
import { Button } from '@mantine/core';

function MyButton({ myProp, ...others }) {
  return <Button {...others} />;
}
```

## Should Mantine be used with JavaScript?

We recommend using Mantine with TypeScript. It doesn't require deep knowledge of TypeScript
and will make your code more robust and easier to maintain. For example, you'll get type errors
when you pass invalid props to components or when you use non-existent props. TypeScript will also
help you during migration to new versions of Mantine – you'll get type errors when props/components
that you have in your code are removed/renamed/changed.

If you're not familiar with TypeScript yet, using Mantine with TypeScript will be a great opportunity
to learn it. You can use any of the [templates](https://mantine.dev/llms/getting-started.md) to get started – all of them include
TypeScript support out of the box.
