Script Preparation code:

var arr = []
let i = 0
let len = 100000
for(;i<len;i++) {
	arr.push(i)                
}

Tests:

for
let len = arr.length for(let i = 0;i<len;i++) { if (arr[i] === 99999){ return i } }
prototype.find
const found = arr.find(function(element) { return element === 99999 })
forEach
let foundForEachIndex = -1 arr.forEach(function (item, i){ if (item === 99999){ foundForEachIndex = i return } })
map
let foundMapIndex = -1 arr.map((item, i) => { if (item === 99999){ foundMapIndex = i return i } })
