Script Preparation code:

var arr = []
let i = 0
let len = 1000
for(;i<len;i++) {
	arr.push(i)                
}

Tests:

for
let i = 0 let len = arr.length let foundIndex = -1 for(;i<len;i++) { if (arr[i] > 999){ return i } }
prototype.find
const found = arr.find(function(element) { return element > 999 })
forEach
let foundForEachIndex = -1 arr.forEach(function (item){ if (item[i] > 999){ foundForEachIndex = i return } })
map
let foundMapIndex = arr.map(item => { if (item[i] > 999){ return i } })
