How would you introduce a friend of yours to the current state of JS development?

Hi everybody! I have a friend that would like to learn to code for the web, his knowledge is all about JavaScript of like 7 years ago (he's 23 now), when you had just a single file to add interactivity on a web page.

Yesterday we did a videochat following a videocourse, trying to introduce him into Angular 2, but we had a problem: he finds difficult to follow a tutorial if he isn't understanding every thing that is going on (like why he has to import all those things that he doesn't know what they do).

How could I help him to not feeling fatigued in the very beginning of discovery of all those new things that belong to Angular 2 (and TypeScript)?
