/**
* Returns a new ndarray where the order of elements of an input ndarray along specified dimensions is reversed.

* @param {ndarray} x - input array
* @param {IntegerArray} dims - indices of dimensions to reverse
* @throws {TypeError} first argument must be an ndarray having one or more dimensions
* @throws {RangeError} dimension index exceeds the number of dimensions
* @throws {Error} must provide unique dimension indices
* @returns {ndarray} output array
*
* @example
* var array = require( '@stdlib/ndarray/array' );
*
* var x = array( [ [ 1.0, 2.0 ], [ 3.0, 4.0 ], [ 5.0, 6.0 ] ] );
