Learning curve for ReactJS

I am wondering as I’m about to start learning ReactJS, in your opinion, what is the learning curve (time needed) to effectively use ReactJS ? Btw, I’m jQuery and Angular developer. Thanks.

It took me a little bit to figure out what was going on - it’s a different concept than regular JS. Once it clicked, it made sense. If you’ve done Angular it might be a little easier.

I would suggest looking on youtube and finding some people building projects with React - that was very helpful to me. I found Brad Traversy’s stuff to be helpful, but there are others too,
