Benchmark: JavaScript Array Shallow Copy: Array.from vs Spread Syntax vs Array.prototype.slice vs Array.prototype.concat

Script Preparation code:

const array = [];
for (let i = 0; i < 1024; i++)
  array.push(i);

Tests:

Array.from
const a = Array.from(array);
Spread Syntax
const a = [...array];
Array.prototype.slice
const a = array.slice();
Array.prototype.concat
const a = array.concat();
For Loop Push
const a = []; for (const i of array) a.push[i];
For Loop Assign
const a = new Array(array.length); for (let i = 0; i < a.length; i++) a[i] = array[i];
