What do you guys think of udemy dev courses?

I've, as of today, completed two courses on react and graphql. They were good and in-depth but I would not pay full price for them. I already knew most of the material from YouTube.

Some are very good. Most are okayish. As udemy comes up with $10/any course offer very often, I buy them then.

They tend to range from okay - pretty good. If nothing at all, they provide a clear path and a bit of next steps for what you're trying to learn. They're usually pretty cheap, so it's a sound investment for your learning if you ask me. I've been teaching myself with them for a year now.

They about as useful as trying to code on a blackberry with you hands tied to you balls with fishing line while someone tickles your feet with a feather.
