So now we are going to talk about variables and memory location. But before we define variables, you need to understand that any variable you create in JavaScript is going to be stored in a specific location in your computer. So for example, if you want to create a variable called XP, it's going to be stored in a specific memory location in your computer. And memory locations work like labels. Whenever you store some variable in your computer, it's going to label that box that you are going to store that variable in with that memory location so that whenever you want to retrieve that variable, it's going to know exactly which which memory location to bring you, so that it brings you the best Double that you want. And I'm going to give you a very good example that illustrates this process.

Suppose that you want to store a bunch of books inside some box and you have many many boxes at your home. You will have to label that box that you are going to store your books in with some kind of label and you are given you are going to write on that label just a word some some kind of word like books, so that whenever you want to retrieve and know exactly which box that contains your books, you know exactly that. This specific box contains your books. So you have to give some kind of label so that you will be able to retrieve that box easily without spending a lot of time searching through a lot Have boxes that you have. computers do the same with our variables. They have a lot of variables and each variable has some kind of memory location which is a label and whenever you create a variable, it just assigns a memory location.

So whenever you want to retrieve that variable, it knows which memory location location to bring you
