Sometimes, we want to iterate over object keys in Node.js and JavaScript

In this article, we’ll look at how to iterate over object keys in Node.js and JavaScript.

How to iterate over object keys in Node.js and JavaScript?

To iterate over object keys in Node.js and JavaScript, we use the Object.keys method to get the object’s non-inherited keys in an array.

For instance, we write

Object.keys(obj).forEach((key) => {
  //...
});

to call Object.keys with obj to return an array of non-inherited object string keys.

Then we call forEach with a callback that gets the key from the callback parameter.
