Vue is learnable in a single day. React is almost as easy to learn.

Just hire React devs and give them a couple of days with Vue, no problem

There is a difference in being able to write something that runs and writing idiomatic something which uses all the libraries idiomatically that runs.

If you think everyone, with React on resume, is in the latter category, then I have a bridge to sell to you.

It's more than a couple of days but I have done exactly this and it works fine.

In general Vue holds high conceptual similarity to React so React devs just "get it" straight away. However nearly everything is simpler / easier than it would be in React, so they learn it extremely fast.

Good point. But then again, if the engineer is good, switching between say React, Vue and Svelte shouldn’t be too hard. EDIT: To clarify, I mean picking up one of the three if you already know another one.

I 100% agree. I find it troubling that people are 'hiring for React'. How does a developer possibly learn React without learning the core concepts of HTML, CSS, Javascript and thus adapt to any library? It doesn't make sense to me at all.

That would seem so right? I thought so exactly too. This works when your engineering team is small. But once you go beyond the first level of engineering and its mostly maintenance and updates, the people who apply for the job are not interested in learning new things. They have learnt one thing and want to apply that skill 9-5 and go home. For those roles hiring for react is easier.
