Seconded. I won't recommend it and no one I know has recommended it for a decade. It's hard for someone who doesn't know JS to know which parts has changed and is no longer the way to do things.

https://github.com/getify/You-Dont-Know-JS and

https://eloquentjavascript.net/ are the 2 best source for learning JS.

If you don't have time to read both, just go with https://eloquentjavascript.net/

If one needs to go further, go through http://superherojs.com/ , just ignore links that are dead.
