So in the opening example, we saw that the function we provided logs the current array element to the console. It will execute the function we provide for each element of the array we want to iterate on. It does only one thing but it does it very well. So what is the Array.forEach() method? In essence, this is a very simple method. It’s not a requirement to read the previous articles in order to follow along with the examples in this article. In this article, we will take the example established in the previous articles and show how forEach() can help us. Instead, we’ll take a deep look at how the method works, why we need it, and what it would look like in a typical modern front-end codebase. There won’t be a lot of mentions of your pets and friends either I’m afraid. I will try to avoid `foo` and `bar` or overly complex examples. In this “ JavaScript iteration in the real world” series of articles, I want to share with you some of the most common JavaScript iteration methods using examples that resemble as closely as possible what their usage looks like in the real world. Products.forEach(product => console.log(product)) Log to the console each element of the array If you enjoyed and liked this post, don’t forget to share.Const products = Your valuable feedback, question, or comments about this article are always welcome.
