The data is returned by a callback function. Then we invoke the forEach function with the dot(.) operator. The data that is returned by the function is stored in student. We firstly declare an array of student names and name it appropriately so. Let’s take a closer look at how this is all executed. The above snip is the syntax of a forEach loop in JavaScript. You can perform your desired function out here A great way to traverse an array has been a for loop, and that is exactly what the forEach loop improves upon. It’s generally great for maintaining a list of things, for example, student information, which could be stored as a student object in an array. So if you were to count from 1 to 10, you would implement a loop that loops ten times, and increases a counting value by 1.Īrrays are simply put, a collection of similar objects. Loop is the term for the process of implementing an iterator i.e. Below are the topics that we will be looking into: Today we are going to discuss one particular loop that has quickly turned into a favourite amongst developers the forEach loop in JavaScript. JavaScript provides a multitude of ways for implementing loops to traverse through an array.
