Script Preparation code:

var array = [1, 3, 2];

for(let i = 0; i < 6; i++) {
	array.concat(array);
};

Tests:

Array.forEach
array.forEach(d => { console.log(d); });
for(const value of array)
for(const value of array) { console.log(value); };
index
for(let index = 0; index < array.length; index++) { console.log(array[index]); };
Array.reverse + reversed index
array.reverse(); for(let index = array.length - 1; index >= 0; index--) { console.log(array[index]); };
