Where to begin after 3 years out of code

Reposting this here based on advice from learn to program subreddit

Posting here because truthfully I feel like I'm back at 0.

But not sure what's new, what important to focus on or what's dead...

So many new languages and changes in this frame I'm not sure where to start (whether to try and pick up or start from scratch that is)

Just wondering if anyone here can recommend some at least items to look at or focus on.. I looked at some possible boot camp or classes, but the cost of $1k++ and commiting full-time hours I can't provide while trying to pay bills living in Toronto...

Any advice, or if this is wrong sub please let me know..
