Hey Michael!
In general you will be okay.
I do use some JS in the API content that I actually haven’t taught yet in part 1 (mostly ES6 and asynchronous JS stuff) so just be ready for things to look a little more advanced, but in general I think you’ll be okay.
The one thing I would recommend though is watching the webpack videos since some of the examples require you to know some basic webpack commands.
Hope that helps!!!
