this,props.score

HI! I'm really enjoying this React course as it seems to be a challenge. I'm fairly understanding everything as we progress. I just would like if someone can re iterate in words why we put the this. Is the this connected to the class itself?

Hey,

If you notice; React.createClass takes an object as argument, so "this" will point to that object.

So, when you use your new class to create a new component and pass prop to that component class, "this" will points to that component(object) and this.props will point to that object propTypes.

I am sorry I am still having a hard time following. If this.props.score is not used, then what will props.score search for ?

Dead issue, I know...

But, If any future students are looking into this question, take a look at this course if you're having trouble with "this".
