The Object valueOf() Method: A Comprehensive Guide

In JavaScript, the valueOf() method is used to retrieve the primitive value of an object. It is called on an object instance and returns the underlying primitive value.

Here is an example to demonstrate how the valueOf() method works:

const person = { name: 'Fred' };
person.valueOf(); // { name: 'Fred' }

In the above example, the valueOf() method is called on the person object. As a result, the original object is returned.

It’s important to note that the valueOf() method is primarily used internally by JavaScript and is rarely invoked in user code.

By understanding the valueOf() method, developers can better manipulate objects and retrieve their primitive values when needed.
