I do not pretend to be any kind of expert, but on our team we needed to teach people a little bit about TDD as it related to Angular using Typescript with and intro to bundling and a whole slew of other things, so I made a video series that covers synch and async fundamentals inside of that framework using Jasmine: https://www.youtube.com/playlist?list=PLr4KpsL6BPn0dzn84zjmx...
There are tons of really good books out there on the subject from Packt too. React using Jest isn't super widely filmed, but has good docs. If you do become a master, create a video series and help the next guy out. =) Happy coding!
