js for loops

1var colors=["red","blue","green"];
2for (let i = 0; i < colors.length; i++) { 
3  console.log(colors[i]);
4}

1var i; //defines i
2for (i = 0; i < 5; i++) { //starts loop
3  console.log("The Number Is: " + i); //What ever you want
4}; //ends loop
5//Or:
6console.log("The Number Is: " + 0);
7console.log("The Number Is: " + 1);
8console.log("The Number Is: " + 2);
9console.log("The Number Is: " + 3);
10console.log("The Number Is: " + 4);
