Return the layout order of a provided ndarray.
npm install @stdlib/ndarray-base-orderWe 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. 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. 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. To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!

> Return the [layout order][@stdlib/ndarray/orders] of a provided [ndarray][@stdlib/ndarray/base/ctor].
``bash`
npm install @stdlib/ndarray-base-order
`javascript`
var order = require( '@stdlib/ndarray-base-order' );
#### order( x )
Returns the [layout order][@stdlib/ndarray/orders] of a provided [ndarray][@stdlib/ndarray/base/ctor].
`javascript
var zeros = require( '@stdlib/ndarray-zeros' );
var x = zeros( [ 3, 2, 3 ], {
'order': 'row-major'
});
// returns
var out = order( x );
// returns 'row-major'
`
`javascript

var slice = require( '@stdlib/ndarray-slice' );
var E = require( '@stdlib/slice-multi' );
var S = require( '@stdlib/slice-ctor' );
var order = require( '@stdlib/ndarray-base-order' );
// Create an array:
var x = zeros( [ 10, 10, 10, 10 ] );
// returns
// Define some slices:
var slices = [
// :,:,:,:
E( null, null, null, null ),
// 5:10,4,2:4,::-1
E( S( 5, 10 ), 4, S( 2, 4 ), S( null, null, -1 ) ),
