JavaScript has an Array type for storing a list of values. You can iterate over this array to perform various operations on each item in the array. There are two ways to do so: with a for loop or using the built-in JavaScript function called .forEach() that can only be used when iterating over arrays or instances of java.lang.iterable .

This blog post will explore how you can use both methods and which is best suited for your situation, as well as some cool things you can do with either method! The first thing we need to know is what kind of object our array contains, such as strings, integers, booleans etc., before deciding which method to use.

For the purpose of this example, we will assume that our array contains strings. For loops are a very common and often simple way to iterate over an array in JavaScript. With for loops you write a code block for every iteration, which is then executed once per item in the list or on each successive index marker from 0 up to (but not including) length-value .

This enables us to work with one value at the time, but it doesn’t allow chaining operations like .map() or .filter() calls together so developers need to break their statements into multiple lines if they want them all processed sequentially: var colors = [‘red’, ‘blue’]; // Create new variable var color; // Use loop.
