Script Preparation code:
const list = new Array(1000).fill("value"); const list2 = new Array(1000).fill("value"); const list3 = new Array(1000).fill("value"); const list4 = new Array(1000).fill("value");
Tests:
Move Indexes
let i = 100; while (i < 1000) { list[i - 100] = list[i]; i++; } list.length = 900;
Shift
let i = 0; while (i < 100) { list2.shift(); i++; }
Splice
list3.splice(0, 100);
Slice
list4.slice(100);
