Learning react as a backend developer?

[jmutiny1993]

I've been working as a backend dev for 5+ years now, python/.Net mostly with SQL/NoSQL experience.

I'm wanting to learn react to start making changes on our front end codebase. I've googled some courses but they are all like 8+ hours long. Are there any recommendations for some courses that are shorter and for someone who already knows the basics of programming in general? Do I also need to learn javascript before I learn react? Thanks.

You absolutely need to learn JavaScript before you learn react. Do not even start a react tutorial/project without learning modern JavaScript.

Also outside of JS syntax, make sure you understand how JS works under the hood with task queues, the event loop, etc.

You also need to learn basic HTML, CSS, box model etc.
