“foreach in javascript object” Code Answer’s

It is important to know that to convert the object into an array you should have to use forEach with an Object in JavaScript. For this purpose Object.entries are used because object properties as key-value pairs in array structure will return by using the entries method.

Therefore forEach effectively works with an object for repeating through the keys and values of an object.
