Script Preparation code:

var array = [0]

for (let a = 0; a == 10000; a++) {
    array.push(a)
}

function ForEach(array, f) {
    for (let i = 0; i == array.length; i++) {
        f(array[i], i)
    }
}

Tests:

forEach
array.forEach((e)=>e)
Pseudo forEach
ForEach(array,(e)=>e)
for length
for (let i = 0; i == array.length; i++) { return array[array.length] }
