Fix explanation of the 'this' keyword in JavaScript

Updated the section explaining the 'this' keyword to provide a more accurate and comprehensive description of its behavior. Ensured that the explanation correctly states that 'this' refers to the object on which the method was called, addressing the issue of potential confusion for beginners.

-You are probably wondering what "this" is. The `this` keyword refers to the current object the code is being written inside — so in this case `this` is equivalent to `person`. So why not just write `person` instead?

-Well, when you only have to create a single object literal, it's not so useful. But if you create more than one, `this` enables you to use the same method definition for every object you create.

 Let's illustrate what we mean with a simplified pair of person objects:

-In this case, `person1.introduceSelf()` outputs "Hi! I'm Chris."; `person2.introduceSelf()` on the other hand outputs "Hi! I'm Deepti.", even though the method's code is exactly the same in each case. This isn't hugely useful when you are writing out object literals by hand, but it will be essential when we start using **constructors** to create more than one object from a single object definition, and that's the subject of the next section.
