You can then iterate over each key in the object using forEach(). Description: A generic iterator function, which can be used to seamlessly iterate over both objects and arrays. JavaScript objects are collections of key-value pairs, where each object key (also called object property) has a specific value. 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(). Instead of using a for loop, we’re going to use a forEach loop. We’re going to write a loop that displays a list of companies to the console. ![]() Lists, sets, and all other list-like objects support the forEach method. JavaScript's Array#forEach() function lets you iterate overīut not over an object. It is used to execute a function on each item in an array.
