How can i pass an object as a perameter to a function and return an object from a function?

JavaScript

In JavaScript, you can pass an object as a parameter to a function by simply including it in the function's parameter list. For example:

<code class="language-JavaScript">function processObject(obj) {
// Modify or work with the object obj.newProperty = 'New Value'; return obj; // Return the modified object }
</code>

You can call this function like so:

<code class="language-JavaScript">const myObj = { existingProperty: 'Old Value' };
const updatedObj = processObject(myObj);
</code>

Here, updatedObj will contain the modified object with the new property added.
