Why can't you use this.string and instead you're using myString.string?

It might help if you post some code for context. Without seeing that code, I would suggest you think about what "this" is referring to at any point. It's a subject with some depth, but the basic jargon is that it is determined by the invocation setting. I haven't looked at the code or the challenge yet, but I suspect "this" is being avoided because it would refer to something happening in a parent function or a prototype, rather than the instance "myString" represents.

I think Barry above hit the spot with the answer - but just to perhaps add some clarity, as I have been following the video of this practice - the instructor does use the "this" keyword when referencing a property within the object declaration. In that context - "this" refers to the object and therefore using .dot notation on the object is valid. However, when she posts or console.logs the array - "this" wouldn't be referring to "myString" at that point or in that context. In fact if you try console.log with keyword "this" you will see that the value is undefined.

I got 

countWords() {return this.string.split(" ").length}

to work.
