	return x.data;
}
Returns the underlying data buffer of a provided ndarray.

@param {ndarrayLike} x - input ndarray
@returns {Collection} underlying data buffer

@example
var zeros = require( '@stdlib/ndarray/zeros' );

var x = zeros( [ 3, 3, 3 ], {
    'dtype': 'float64'
});

var out = data( x );
// returns <Float64Array>
