Echo JS 0.11.0

PSA: the current version of Angular is 7.2 and v8 is due in April.

I'm generally skeptical of posts for "courses" on this and similar sites.  In particular, at a glance, I don't know if this is a really free site, if some courses are free, or you can complete the lessons with or without payment.  I don't have a problem with people wanting to get paid, but one really needs to be skeptical, there's a lot of junk.

Also, as MaxArt mentions, v5 is a few versions behind, but Angular had had far fewer breaking changes between versions since v3-4.  The workflows are pretty solid.

I'm personally not a fan of Angular and prefer React+Redux+thunks/fetch myself YMMV but every time I've used or worked with Angular, I'm reminded of why I don't care for it.
