In this video Simon explains the method of querySelectorAll in JavaScript. He used it for a SVG challenge from LearnWebCode. Unfortunately, after several hours of work, when he was nearly there, the project failed (my assumption is that it was due to a P5 failure). They use a different editor in the tutorial but Simon couldn’t understand which one, so he used the P5. Simon cried for a short while but quickly switched to a new project. I have noticed a while ago that he is much more interested in the learning process than the actual product, which I think is a very healthy learning attitude.
Geeks out of the box
