Script Preparation code:

arr = Array.from({length: 1000}, (_, i) => i);

Tests:

Initial value indexing
const index_zero = arr[0]; console.log(index_zero);
Random value indexing
const index_random = arr[Math.floor(Math.random() * arr.length)]; console.log(index_random);
Last value indexing
const index_last = arr[arr.length - 1]; console.log(index_last);
Initial value at()
const at_zero = arr.at(0); console.log(at_zero);
Random value at()
const at_random = arr.at(Math.floor(Math.random() * arr.length)); console.log(at_random);
Last value at()
const at_last = arr.at(-1); console.log(at_last);
