Ask HN: Have you done any courses by Devslopes ?

Hi, I have experience doing backend with Python (Flask) and RoR. Now I would like to learn the javascript stack as well. I don't mind spending some money if it saves me time.

Devslopes offers a backend course which seems to be exactly what I am looking for. Unfortunately, they don't have a free sample chapter.

Has anybody of you taken one of their courses or perhaps even their backend course?
