Hi everyone. I’m up to POST requests now but I’m struggling to understand the concept of requests. Is it so we can use information from other websites?

I also feel like I am not learning anything new with this lesson. This is not like the previous chapters in the course. Hopefully it will be explained more thoroughly as we go along.

I am curious why this function does not follow the usual Camel case syntax ?
xhr.onreadystatechange()

Why xhr.onreadystatechange function handler has to be an arrow syntax but not function expression?
Why this works?
xhr.onreadystatechange = () => {};
But this doesn’t
xhr.onreadystatechange = function() {
};

Hey guys I’m so confused the exercise only asked us to add a property responseType to the xhr object (task 3) but then asks us to return the response property of xhr (task 6). Shouldn’t it be responseType or am I missing something here?
This exercise is basically copy the text from the image we showed you two seconds ago without further explanation whatsoever. cmon guys.

I’m not doing so hot with this module BUT I think I can help here.
I believe the response TYPE determines the format of what is returned. In this case, a json file will be returned. The response should the file itself.
We are saying “hey, i need a repsonse in the form of a json file” and the server says “i gotchu, here ya go” and sets it equal to the response property for xhr?

It would be helpful if someone indicated that this response is correct! Or not - but that would require further explanation

Why is onreadystatechange used instead of onload?
