There is some really good stuff in here and this will teach you JavaScript well. However sound quality varies, it is sometimes quite poor and the teachers could have refined and improved their examples more before publishing the content.

Looking to learn. So far so good.

why are these questions asked so early?

Very good, thank you
By Bob Bunger on 10/25/2020
ok so far, could use more engaging examples, and explain why putting js in the script tags directly is done in between the script tags, whereas adding a js file is done as an attribute of script tags, instead of in between the script tags. doesnt make sense.

Maybe give more direction on possible errors people may receive and how to fix them.

By Barbara Yothers on 9/25/2020
It may be. It's slow going for a total beginner.
By Pawel Broilo on 9/22/2020
I think the JavaScript course is very comprehensive.
