Benchmark: Cloning an array

Script Preparation code:

var array = [];
for (let m = 0; m < 40; m++) {
  array.push(m);
}

Tests:

Using array slice
let clone = array.slice();
Using array spread
let clone = [...array];
Using array push and spread
let clone = []; clone.push(...array);
Using for loop and push
let clone = []; for (let i = 0; i < array.length; i++) { clone.push(array[i]); }
Using array concat
let clone = [].concat(array);
