Hello, and welcome, @ats3788!

JavaScript is a [garbage-collected](https://en.wikipedia.org/wiki/Garbage_collection_(computer_science)) language, so you don’t have to explicitly remove or free the object. The object will be kept around as long as something is referencing it.

What you can do is make sure that nothing is referencing the object, like:

```javascript
b = undefined;

```

With no more references, the garbage collector will eventually take care of and free the memory.
