Script Preparation code:
var arr = []; var i = 0; while (i <= 1E5) arr[i] = i++;
Tests:
Array.prototype.find
const item = arr.find(item => item == 1E5);
Array.prototype.findIndex
const index = arr.findIndex(item => item == 1E5);
Array.prototype.indexOf
const index = arr.indexOf(item => item == 1E5);
