import { Collection } from '@stdlib/types/array';

/**
* Removes and returns the last element of a collection.
*
* ## Notes
*
* -   The function returns an array with two elements: the shortened collection and the removed element.
* -   If the input collection is a typed array whose length is greater than `0`, the first return value does not equal the input reference.
* -   For purposes of generality, always treat the output collection as distinct from the input collection.
*
* @param collection - collection
* @returns updated collection and the removed element
*
* @example
* var arr = [ 1.0, 2.0, 3.0, 4.0, 5.0 ];
*
* var out = pop( arr );
* // returns [ [ 1.0, 2.0, 3.0, 4.0 ], 5.0 ]
*
* @example
* var Float64Array = require( '@stdlib/array/float64' );
*
* var arr = new Float64Array( [ 1.0, 2.0, 3.0, 4.0, 5.0 ] );
* // returns <Float64Array>[ 1.0, 2.0, 3.0, 4.0, 5.0 ]
*
* var out = pop( arr );
* // returns [ <Float64Array>[ 1.0, 2.0, 3.0, 4.0 ], 5.0 ]
