// MAIN //

/**
* Copies elements from an input strided array to elements in a strided DataView.
*
* @param {NonNegativeInteger} N - number of indexed elements
* @param {Collection} x - input array
* @param {integer} strideX - `x` stride length
* @param {DataView} view - output DataView
* @param {integer} strideView - `view` stride length (in bytes)
* @param {boolean} littleEndian - boolean indicating whether to store the data in little-endian format
* @returns {DataView} output DataView
*
* @example
* var ArrayBuffer = require( '@stdlib/array/buffer' );
* var DataView = require( '@stdlib/array/dataview' );
*
* var x = [ 1.0, 2.0, 3.0, 4.0 ];
*
* var buf = new ArrayBuffer( 32 );
* var view = new DataView( buf );
*
* var out = writeDataView( 4, x, 1, view, 8, true );
* // returns <DataView>
*
* var bool = ( out === view );
* // returns true
*
* var v = view.getFloat64( 0, true );
* // returns 1.0
