> Create a throttled function that runs at most once per interval, limiting how often expensive handlers fire during rapid events.

## Usage

`throttle` wraps a function so that it executes at most once within the specified time interval.

```ts
import { throttle } from '@movk/core'

const throttledScroll = throttle((event: Event) => {
  console.log('Scroll event handled')
}, 100)

// Listen to scroll events, executing at most once every 100ms
window.addEventListener('scroll', throttledScroll)
```

## API
