Have you seen that Flanagan's JavaScript the Definitive Guide, the famously big book with the rhinoceros on its cover, has recently seen a new edition? I wonder how deep its JavaScript goes :-)

David has written about what's new, if anyone's interested: https://davidflanagan.com/2020/05/03/changes-in-the-seventh-...

I also (briefly) interviewed him about it here: https://superhighway.dev/david-flanagan-interview

No PDF version?

I've always enjoyed the famously small book "Javascript: The Good Parts", albeit a bit dated at this point

Unfortunately, the language has changed so much in recent years that I wouldn’t necessarily recommend that book anymore. A large number of fundamental features have been introduced since 2008, including async/await, lambda functions, class and extends syntax, proxies, and a ton of builtin methods like map() and forEach() on native list types.

For sure, these were the old days before jQuery was even considered a standard library. It was still duking it out with YUI and Prototype.

I'm fairly sure Lambda functions have always been part of javascript?

function () {}'s have been there forever, but () => {}'s have different semantics and are somewhat new

Anonymous functions indeed have. I think he means the arrow function syntax.

Yes, my bad. I meant arrow functions.
