    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

```

</section>

<section class="usage">

## Usage

```javascript
var without = require( '@stdlib/array-base-without' );
```

#### without( x, index )

Returns a new array containing every element from an input array, except for the element at a specified index.

```javascript
var x = [ 1, 2, 3, 4 ];

var out = without( x, 0 );
// returns [ 2, 3, 4 ]

out = without( x, -1 );
// returns [ 1, 2, 3 ]
```

The function accepts the following arguments:

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

### without.assign( x, index, out, stride, offset )

Copies every element from one array to another array, except for the element at a specified index.

```javascript
var x = [ 1, 2, 3, 4 ];

var out = [ 0, 0, 0 ];
var arr = without.assign( x, 0, out, 1, 0 );
// returns [ 2, 3, 4 ]

var bool = ( arr === out );
// returns true
```

The function accepts the following arguments:

-   **x**: an input array.
-   **index**: element index.
-   **out**: output array.
-   **stride**: output array stride.
-   **offset**: output array offset.

## Notes

-   Negative indices are resolved relative to the last array element, with the last element corresponding to `-1`.

## Examples

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

```javascript
var discreteUniform = require( '@stdlib/random-array-discrete-uniform' );
var without = require( '@stdlib/array-base-without' );

// Define an array:
var opts = {
    'dtype': 'generic'
};
var x = discreteUniform( 5, -100, 100, opts );

// Define an array containing random index values:
var indices = discreteUniform( 100, -x.length, x.length-1, opts );

// Randomly omit elements from the input array:
var i;
for ( i = 0; i < indices.length; i++ ) {
    console.log( 'x = [%s]', without( x, indices[ i ] ).join( ',' ) );
}
