## README

# throttleit

> Throttle a function to limit its execution rate

## Install

```sh
npm install throttleit
```

## Usage

```js
import throttle from 'throttleit';

// Throttling a function that processes data.
function processData(data) {
	console.log('Processing:', data);

	// Add data processing logic here.
}

// Throttle the `processData` function to be called at most once every 3 seconds.
const throttledProcessData = throttle(processData, 3000);

// Simulate calling the function multiple times with different data.
throttledProcessData('Data 1');
throttledProcessData('Data 2');
throttledProcessData('Data 3');
```

## API

### throttle(function, wait)

Creates a throttled function that limits calls to the original function to at most once every `wait` milliseconds. It guarantees execution after the final invocation and maintains the last context (`this`) and arguments.

The throttled function returns the result of the most recent execution of the original function. When a call is deferred, it returns the result from the previous execution (or `undefined` if it has not executed yet).

#### function

Type: `Function`

The function to be throttled.

#### wait

Type: `number`

The number of milliseconds to throttle invocations to.

Must be a non-negative finite number.
