var medium = Array.from({ length: 100 }, (_, i) => i);
var large = Array.from({ length: 1000 }, (_, i) => i);

var xxxxlarge = Array.from({ length: 10000000 }, (_, i) => i);

var filter = (arr, index) => arr.filter((_, i) => i !== index);

var slice = (arr, index) => [...arr.slice(0 ,index), ...arr.slice(index+1)];
