Syntax and Parameters of a forEach() Loop Note: Arrays are collections of elements that can be of any datatype.

This function is referred to as a callback function. The forEach() array method loops through any array, executing a provided function once for each array element in ascending index order. It is entirely up to you whether or not to use a specific loop method, but it is important that we understand each of them and how they work. There are many iteration methods in JavaScript, including the forEach() method, and they almost all perform the same function with minor differences. In this article, we'll look at how you can use the JavaScript forEach() array method to loop through all types of arrays, as well as how it differs from the for loop method. These arrays can hold any datatype, including objects, numbers, strings, and many others.

When working with arrays, there will be times when you need to loop or iterate through the array's values in order to either output or manipulate them.
