One year ago you were job searching & didn’t even know what to do with programming & now you suddenly know everything… lol.
Guess you forgot., let me remind you: Where to go next?
And I quote you:
“Yeah, that was another thing that I considered. I had a lot of that stuff when I studies C, decades ago. I’ve thought about going through and building all those old data structures and algorithms in JS. I’m not sure how applicable they are to modern coding, but they do appear to be a touchstone for some interviewers.”
