Fruitful resources to improve Javascript knowledge

No matter you're a beginner at learning Javascript stuff or a person who familiar with the ecosystem well, you could miss something. I gather here common and specific Javascript and Node.JS resources that could be handy for you.

Well explained topics if you want to deepen to low-level stuff. How the V8 handles Javascript types internally? How does the compiler work?

The Crankshaft pipeline example (simplified)

It also covers garbage collector, memory/performance profiling, code caching subjects.

  • V8 source code
  • Official website - I recommend you to check out their blog, a lot of great topics covered. Also, they post information about newly released versions of the engine and other updates.

WTF, Javascript?

A list of funny and tricky JavaScript examples.

Useful examples with explanations for beginners and nice-to-know for all Javascript developers.

NaN === NaN; // -> false

// ----------------------
typeof NaN; // -> 'number'

Examples of implementations of handy functions you use often.

How to write cross-platform Node.js code

Why you should care: according to the 2018 Node.js user survey, 24% of Node.js developers use Windows locally and 41% use Mac. In production 85% use Linux and 1% use BSD.

Sometimes you should think about compatibility with other platforms. Good questions covered - for example, why you should point an encoding when reading a file or warn you that os.cpus() is always 0 on Windows.
