You’ve cut off some important context here:

Nobody wants to watch a 30-minute video for something that can be summed up in a 250-word article.

I’m fine with watching a 30-minute video if that format adds value. It doesn’t here, just gimme a write-up.

First of all, the article talks about JavaScript, not Java. Secondly, who writes “Java” in all caps?

CSS now is… a tad more complicated than it was 25 years ago, FYI.

There’s a difference?

I’m curious as to why you’d want to? The audio quality is pretty atrocious due to the compression they use, and—last time I tried, anyway—all their channels are full of obnoxious interruptions for self-promotion.

“performance”

“mistakes”

Only NOW?
