});for each js
const fruits = ['mango', 'papaya', 'pineapple', 'apple'];
// Iterate over fruits below
// Normal way

console.log('I want to eat a ' + fruit)
});js for each item do
let array = ['Item 1', 'Item 2', 'Item 3'];
array.forEach(item => {
console.log(item); // Logs each 'Item #'
});foreach in javascript
///Simple One
var a = ["a", "b", "c"];
a.forEach(function(entry) {
console.log(entry);
});
///Function concept
var fruits = ["apple", "orange", "cherry"];
fruits.forEach(myFunction);
function myFunction(item, index) {
document.getElementById("demo").innerHTML += index + ":" + item + "<br>";
}what is foreach method in javascript
var arr = [1, 2, 3, 4, 5, 6];
//var sum = 0;
arr.forEach(function (value, index, array){ // Built in method
//sum += value;
console.log(value, index, array);
})
//console.log(sum); // We can print sum of all Array element (if those are numbers)
// function forEach(arr, cb){ // How forEach() method works
// for (var i = 0; i<arr.length; i++){
// cb(arr[i], i, arr);
// }
// }
// var sum = 0;
// forEach(arr, function (value, index, arr){
// console.log(value, index, arr);
// sum += value;
// })
// console.log(sum);javascript for each loop
const a = ["a", "b", "c"];
for (const val of a) { // You can use `let` instead of `const` if you like
console.log(val);
