    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>

## Usage

```javascript

#### sliceShape( slice )

Returns the shape of a [normalized multi-slice][@stdlib/slice/base/normalize-multi-slice].

<!-- eslint-disable new-cap -->

```javascript
var S = require( '@stdlib/slice-ctor' );
var MultiSlice = require( '@stdlib/slice-multi' );
var normalizeMultiSlice = require( '@stdlib/slice-base-normalize-multi-slice' );

var s = new MultiSlice( S( -4, null, -1 ), S( 2, 10, 1 ) );
// returns <MultiSlice>

s = normalizeMultiSlice( s, [ 10, 10 ], false );
// returns <MultiSlice>

var sh = sliceShape( s );
// returns [ 7, 8 ]
