- An inability to work without frameworks. Lots of devs know React/Angular/Vue/whatever, but have a tenuous grasp of vanilla JavaScript
- Lack of computer science/algorithm knowledge. True of myself, and a lot of self taught developers.

From what I've seen:
- An inability to work without frameworks. Lots of devs know React/Angular/Vue/whatever, but have a tenuous grasp of vanilla JavaScript
- Lack of computer science/algorithm knowledge. True of myself, and a lot of self taught developers.
- Lack of CSS knowledge. Quite a few devs know a decent amount of HTML, a decent amount of JavaScript (including one or two frameworks) but haven't brushed up on their CSS knowledge in a while. So they'll not know modern additions to the language, or in the worst cases, not know stuff like Grid or Flexbox.

I've got half-my-mind to simply abandon all framework and language learning and chasing, and just do / learn HTML and CSS properly.
Nobody would hire you for that though.
But HTML and CSS aren't really that hard. A weekend of focus and you can probably become proficient in both.
