I watched the introducing React video and at the end, Guil mentions that you should have some familiarity with JS because you can't really learn both at the same time. Where are the prerequisites? The only thing I see is recommended courses which to me seems like other courses that are similar to this one that you jmay also want to check out.

Treehouse Guest TeacherHi Kevin, just below the video, in the teacher's notes section, there is a list of some courses that would be good to complete before diving into React.
https://teamtreehouse.com/library/objectoriented-javascript-2 https://teamtreehouse.com/library/javascript-array-iteration-methods https://teamtreehouse.com/library/getting-started-with-es2015-2
If you've completed those courses and are comfortable with the material in them, then you're likely to fare better while learning React.
Hope that helps.

4,225 PointsI learned the basics of javascript. How familiar and proficient do I have to be to start learning React. I have a basic understanding but not solid knowledge of javascript. Thank you.
