for loop in javascript

var colors=["red","blue","green"];
for (let i = 0; i < colors.length; i++) { 
  console.log(colors[i]);
}for (var i; i < 10; i++) {
  
}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!let str = "";

for (let i = 0; i < 9; i++) {
  str = str + i;
}

console.log(str);
// expected output: "012345678"
var i;
for (i = 0; i < cars.length; i++) {
  text += cars[i] + "<br>";
}For printing 0 to 9

you can write like below also
var i;
for (i = 0; i < 10; i++) {
  console.log(i);
}
