Benchmark: spread array performance (vs slice, splice, concat, Array.from)

Tests:

Splice
const testArray = [1, 2, 3]; const newTestArray = testArray.splice(0);
Slice
const testArray = [1, 2, 3]; const newTestArray = testArray.slice();
Concat
const testArray = [1, 2, 3]; const newTestArray = testArray.concat();
Spread
const testArray = [1, 2, 3]; const newTestArray = [...testArray];
Array.From
const testArray = [1, 2, 3]; const newTestArray = Array.from(testArray);
