Broken Arrow says:

Okay… so you very concisely showed how to write javascript, but didn’t really talk about its uses nor rationale. I have zero knowledge of this… so although I understand how to write all the scripts and everything thanks to your video, without a brief ‘this is what this is for… and this is the rationale behind this…’ then I do not know what all this is for. That said, I understood your html, css intros because I had some previous intro to those languages… and you did mention their uses and functions… but this… don’t know. I would need to get the background as to its uses and whatever before I can understand the logic behind random commands.
