I thought any fledgling dev could become a good one with enough team guidance, frequent discussion on ideas and reasoning with seniors, experience, and work variety

But one I know is proving they don't have the knack.

I really wanted to believe anyone could be a good dev if they tried hard enough but this one is just...

They've dragging us down.
Not paid enough to make it my problem to raise it with management. I've tried to help them grow but I've never seen such slow growth despite the different learning/teaching styles *we've* done to improve their capabilities (the entire team)

I dread working with them and I'm not alone apparently

Man, I fucking hate browsers. Some of them move at a snails pace when it comes to APIs, and polyfills and bloated frameworks pop up to work around it.

I know it's pretty much impossible, but get together and actually implement the features you're missing from each other, fuck.
