Benchmark: array slice vs while loop

Script Preparation code:

const items = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16];
const startIndex = 0;

Tests:

While
const endIndex = 14; let index = startIndex; const trimmedItems = []; while (index <= endIndex && index < items.length) { trimmedItems.push(items[index]); index++; }
slice
const trimmedItems = items.slice(startIndex, 15)
