Re: "Example: reading text lines asynchronously".

It seems readline module can simplify implementation so that splitLines() step can be eliminated. See an example:

Possible typos:

1. "It’s implementation is relatively complex...": It’s -> Its?
2. "Channels feels like a good abstraction...": feels -> feel?

Hello, and thank you for the book. Sorry if this question is not relevant here. Can we test these features out yet, does babel have a 2019 preset?

@rauschma Was gonna report a typo, but @vsemozhetbyt already beat me to it. ☻

Your writing is fantastic, and outshines almost everything else on cutting-edge Javascript I can find. Thank you so much!

@vsemozhetbyt @Zearin Thanks! The typos will be fixed in the next release.

@vsemozhetbyt Regarding your other two comments:

1. I wanted to explicitly show how normal callback-based reading of data works in Node.js, so the example is deliberately more complicated than it needs to be.
2. Links: will be fixed in the next release, thanks!

Please provide the link to the AsyncQueue implementation in section 5.4.3.
https://github.com/rauschma/async-iter-demo/blob/master/src/async_iter_tools.js

I had a hard time wondering what "example repo" you mean, finally finding it in the according blog post.

Otherwise thank you for the enjoyable book!

I only bring this up because of how consistently clear and helpful the rest of this and your other books are, but there is a missing comma separating the method properties next() and _run() of the object literal showing "a rough approximation of how async generators work" in 5.3.2. await in async generators. Really this is just a reason to say thank you--wish I had found these books when I first started (even made it possible for me to write this comment correctly)!

*While this isn't in the newer editions, examples like these I found helpful.
