Returns the last element of an array-like object.

var x = [ 1, 2, 3 ];

var out = last( x );
// returns 3

Examples

var Complex64Array = require( '@stdlib/array-complex64' );
var realf = require( '@stdlib/complex-float32-real' );
var imagf = require( '@stdlib/complex-float32-imag' );
var last = require( '@stdlib/array-base-last' );

// Create a complex number array:
var arr = new Complex64Array( [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0 ] );

// Return the last element:
var out = last( arr );
// returns <Complex64>

var re = realf( out );
// returns 5.0

var im = imagf( out );
// returns 6.0

console.log( '%d + %di', re, im );
// => '5 + 6i'
