This method is different from the traditional approach as it uses a functional approach. ![]() In JavaScript, we have another modern approach to iterate the array which is by using the forEach method. One of the most common methods is using the traditional for loop. You can then iterate over each key in the object using forEach(). var family new Array() family0 new Person(alice, 40) family1 new Person(bob, 42). Iterating through an array in JavaScript can be done in multiple ways. In computer programming, foreach loop (or for-each loop) is a control flow statement for traversing items in a collection. The Object.keys() function returns an array of the object's own enumerable But you can iterate over a JavaScript object using forEach() if you transform the object into an array first, using Object.keys(), Object.values(), or Object.entries(). When you return, you skip the rest of the forEach() callback and JavaScript goes on to the next iteration of the loop. It allows you to iterate through each item of a given list and do. ![]() ![]() JavaScript's Array#forEach() function lets you iterate overīut not over an object. For practical purposes, return in a forEach() callback is equivalent to continue in a conventional for loop. For Each loops are the most common type of loop used in building backend projects.
