JavaScript with LinkedIn Learning, Day 4

Just a short post today. I’ve been following up on the practice exercises from last time, building a class and using it to create objects.

Fun Little Tidbits Special Commenting Trick: First, I learned that you can put your cursor on a line of code (or highlight multiple lines) hit CTRL+/ in order to comment out those line(s). Probably old news for some people, but absolutely magic… Read moreJavaScript with LinkedIn Learning, Day 1(ish)
