You can also follow it in the visualizer by clicking on the Show Code Lens button. Let’s see the output in the below section and check if our list of arrays iterates properly or not.What do you think the following code will print out? First trace through it on paper keeping track of the array and the index variable. Though this is not mandatory, you may design it in your own interest. We also include our CSS file and give some styles so that the data can be visible in a nice way. Here, we simply print the list of the student names with the help of the forEach loop.

See the below code example of JavaScript forEach() loop. Though we will demonstrate an example of forEach() loop in JavaScript before jumping into the react.
