You-Dont-Know-JS

I'm surprised that Kyle Simpson's, _You Don't Know JS_ hasn't been mentioned in this thread. https://github.com/getify/You-Dont-Know-JS When I was beginning to develop a deeper understanding of JS a few years ago, that book, Kyle's talks, and conference presentations by Chrome's V8 team were very helpful for me. It looks like Kyle has expanded the content considerably since then too.

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.

Second this recommendation. There's been a lot of changes to JS recently, but it's still worth reading The Good Parts because I think it's philosophically a good way to approach JavaScript. It can be a good language if you know which parts to avoid, and which quirks to look out for. There's also https://github.com/getify/You-Dont-Know-JS as a good follow-up to The Good Parts.

Kyle Simpson "You don't know JS" - I read the first edition cover to cover, and can unreservedly recommend it. https://github.com/getify/You-Dont-Know-JS

There are 6 books, the author recommends reading them in an order: https://github.com/getify/You-Dont-Know-JS?tab=readme-ov-fil... If the second edition is not available, you can read the first edition, just be aware some small things may be slightly out of date.

I remember "JavaScript: The Good Parts" by Douglas Crockford touched some parts in depth. Also "You Don't Know JS Yet" has some depth in it https://github.com/getify/You-Dont-Know-JS

You Don't Know JS by Kyle Simpson. The PDFs are one of the most starred repos on GitHub: https://github.com/getify/You-Dont-Know-JS Also more to your question, "The Browser Hacker's Handbook" and "The Web Application Hacker's Handbook" I also think are really helpful in understanding how browsers work. Sadly a not better documented subject. Visiting the list of APIs on Mozilla's website is also helpful. https://developer.mozilla.org/en-US/docs/Web/API

thanks, I found this one too: https://github.com/getify/You-Dont-Know-JS/blob/2nd-ed/LICEN...

You should check out the free online ebook series You Don't Know JS [0]. Go straight to the last book in the series, called "ES6 & Beyond" [1] which specifically covers the most important features of JavaScript that have appeared since you last worked with it. For hands on practice with newer JS features, the best resource is Execute Program's "Modern JavaScript" [2] course. Once you work through that, move on to their TypeScript Basics course [3]. Both are amazing. Execute Program is the best tool for learning a programming language that I've ever used. [0]: https://github.com/getify/You-Dont-Know-JS/blob/1st-ed/READM... [1]: https://github.com/getify/You-Dont-Know-JS/blob/1st-ed/es6%2... [2]: https://www.executeprogram.com/courses/modern-javascript [3]: https://www.executeprogram.com/courses/typescript-basics

yes, there are a lot of half baked guides and blog posts out there about JS. there are a couple which are really good: https://javascript.info/ - explains good ES6 practices https://github.com/getify/You-Dont-Know-JS which goes in depth in the messy core of the language. nowadays I usually refer to MDN docs and one of the guides like above when guidance is needed.

the fact that there is a long chapter in a book series written on the edge cases of javascript[0] leads me to believe that it's not generally well understood either. 0. https://github.com/getify/You-Dont-Know-JS/blob/1st-ed/async...

I recommend this book https://github.com/getify/You-Dont-Know-JS It discusses great edge cases of JS while explaining why or how come they are like this where possible.
