js for loop

var i; //defines i
for (i = 0; i < 5; i++) { //starts loop
  console.log("The Number Is: " + i); //What ever you want
}; //ends loop
//Or:
console.log("The Number Is: " + 0);
console.log("The Number Is: " + 1);
console.log("The Number Is: " + 2);
console.log("The Number Is: " + 3);
console.log("The Number Is: " + 4);
//They do the same thing!
//Hope I helped!

loop elements in javascript

var list = [{a:1,b:2}, {a:3,b:5}, {a:8,b:2}, {a:4,b:1}, {a:0,b:8}];

for (var i = list.length - 1, item; item = list[i]; i--) {
  console.log("Looping: index ", i, "item", item);
}

######### ES6 Update ################

for (let item of list) {
    console.log("Looping: index ", "Sorry!!!", "item" + item);
}
