How to iterate on arrays with forEach() in JavaScript?

Answer   Submitted by Answiki on 06/15/2020 at 03:19:30 PM UTC

The JavaScript ForEach() function runs a provided function for each array element. Here is an example:

var myArray = ['one', 'two', 'three'];

myArray.forEach( function (item, index) {
	console.log(index, item);
})

// Expected output in the console : 
// 0 "one"
// 1 "two"
// 2 "three"
The forEach() method can also be used with arrow function: 

var myArray = ['one', 'two', 'three'];
myArray.forEach( item => console.log(item));
