for each js array param code example
Example 1: foreach loop javascript
const numList = [1, 2, 3];
numList.forEach((number) => {
console.log(number);
});
Example 2: 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);
