Concat -vs- Spread Operator

Benchmark created on

Description

This test compares the performance of a native .concat to that of a spread operator.

Setup

const arrOne = Array
 				.from({length: 5000})
 				.map( it => (
 					{
 						firstVal: Math.random() * 15, 
 						secondVal: Math.random() * 6 
					}))

const arrTwo = Array
 				.from({length: 5000})
 				.map( it => (
 					{
 						firstVal: Math.random() * 15, 
 						secondVal: Math.random() * 6 
					}))
