loop through an array javascript
let array = ['Item 1', 'Item 2', 'Item 3'];
// Here's 4 different ways
for (let index = 0; index < array.length; index++) {
console.log(array[index]);
}
for (let index in array) {
console.log(array[index]);
}
for (let value of array) {
console.log(value); // Will log value in array
}
array.forEach((value, index) => {
console.log(index); // Will log each index
console.log(value); // Will log each value
});javascript iterate
var obj = {a: 1, b: 2, c: 3};
for (const prop in obj) {
console.log(`obj.${prop} = ${obj[prop]}`);
}
// Output:
// "obj.a = 1"
// "obj.b = 2"
// "obj.c = 3"Iterate with JavaScript For Loops
var myArray = [];
for (var i = 1; i <= 5; i++){
myArray.push(i);
}
console.log(myArray) // console output [ 1, 2, 3, 4, 5 ]how to iterate array in javascript
array = [ 1, 2, 3, 4, 5, 6 ];
//set variable//set the stop count // increment each loop
for (let i = 0; i < array.length ;i++) {
array[i] //iterate through each index.
//add the intructions you would like to perform.
// add any method to array[
}Javascript Iteration
//The forEach() method calls a function (a callback function) once for each array element.const numbers = [45, 4, 9, 16, 25];
let txt = "";
numbers.forEach(myFunction);

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"Copyright © 2021 Codeinu
