I watched videos and read articles until one day it made sense. Also doing the exercises in the javascript console in developer tools from the vdeos and articles. Couldn’t tell you which one it was, but it is necessary to have exposure to the subject outside of FCC. Here’s one video:

Here’s a Google Search:
