The course (called Professor Frisby Introduces Composable Functional JavaScript) is actually free, you just need to enter your email address. Yes, you have to pay for the source code, but if you follow the course from the beginning it might not even be necessary, you can code while watching.
I'd recommend watching the whole course, even without coding along, because it's awesome, really.
Brian has also published a book about functional programming in JS, and it is freely available on Gitbook.

Thanks for your answer. I'll look into that. The book looks great.
