}javascript for loop
var colors=["red","blue","green"];
for (let i = 0; i < colors.length; i++) {
console.log(colors[i]);
}for loop in javascript
For printing 0 to 9
you can write like below also
var i;
for (i = 0; i < 10; i++) {
console.log(i);
}for loop js
let arr = [];
for(let i = 0; i <= 10; i++){
arr[i] = Math.round(Math.random() * 10);
}
• Result: [3, 1, 1, 2, 3, 9, 5, 6, 6, 8, 5]
• Or
let arr = [];
for(let i = 0; i <= 10; i++){
arr[i] = Math.trunc(Math.random() * 10);
}
Result[7, 6, 0, 2, 4, 8, 7, 5, 5, 6, 5]for in js loop
Example:
const object = { a: 1, b: 2, c: 3 };
for (const property in object) {
console.log(`${property}: ${object[property]}`);
}
// expected output:
// "a: 1"
// "b: 2"
// "c: 3"
Syntax:
for (variable in object)
statementjavascript for loop
// for loop keeps running while condition is TRUE
for (let rep = 1; rep <= 10; rep++) {
console.log(`Lifting weights repetition ${rep}`);
}javascript loop through array
// looping through an array in javascript using our own myEach function
// Write an `Array.prototype.myEach(callback)` method that invokes a callback
// for every element in an array and returns undefined.
Array.prototype.myEach = function(callback) {
for (let i = 0 ; i < this.length ; i ++) {
callback(this[i]);
}
}
let array = ['Item 1', 'Item 2', 'Item 3', 'Item 4'];
array.myEach(function (element) {
console.log(element); // this will print each element in the array
// Code to do something to each element in the array
