Tests:
Splice
const testArray = Array(20000).fill().map((_, idx) => idx); const newTestArray = testArray.splice(0);
Slice
const testArray = Array(20000).fill().map((_, idx) => idx); const newTestArray = testArray.slice();
Concat
const testArray = Array(20000).fill().map((_, idx) => idx); const newTestArray = testArray.concat();
Spread
const testArray = Array(20000).fill().map((_, idx) => idx); const newTestArray = [...testArray];
