    About stdlib...
  </summary>
  <p>We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.</p>
  <p>The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.</p>
  <p>When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.</p>
  <p>To join us in bringing numerical computing to the web, get started by checking us out on <a href="https://github.com/stdlib-js/stdlib">GitHub</a>, and please consider <a href="https://opencollective.com/stdlib">financially supporting stdlib</a>. We greatly appreciate your continued support!</p>

## Installation

```bash
npm install @stdlib/array-base-remove-at
```

</section>

<section class="usage">

## Usage

```javascript
var removeAt = require( '@stdlib/array-base-remove-at' );
```

#### removeAt( x, index )

Removes an element from an array.

```javascript
var x = [ 1, 1, 2, 3, 3 ];

var y = removeAt( x, -3 );
// returns [ 1, 1, 3, 3 ]

var bool = ( x === y );
// returns true
```

The function accepts the following arguments:

-   **x**: an input array.
-   **index**: element index.

<!-- Package usage notes. Make sure to keep an empty line after the `section` element and another before the `/section` close. -->

<section class="notes">

## Notes

-   Negative indices are resolved relative to the last array element, with the last element corresponding to `-1`.
-   If provided out-of-bounds indices, the function returns the input array unchanged; otherwise, the function mutates the input array.

</section>

<!-- Package usage examples. -->

<section class="examples">

## Examples

<!-- eslint no-undef: "error" -->

```javascript
var discreteUniform = require( '@stdlib/random-array-discrete-uniform' );
var randi = require( '@stdlib/random-base-discrete-uniform' );
var removeAt = require( '@stdlib/array-base-remove-at' );

// Create an array of random numbers:
var x = discreteUniform( 10, 0, 5, {
    'dtype': 'generic'
});
// returns [...]

console.log( x );

// Remove a random element:
var y = removeAt( x, randi( 0, x.length-1 ) );
// returns [...]

console.log( y );
```
