I see many people talking about advanced concepts of some technologies, or even about JavaScript. I was thinking, where can I learn about advanced concepts? For example, For of is slower than the default for loop because it uses Symbol.iterator (there have overloading, can I say this way?), do you understand? This might be a silly question, but I want to know what you think or what your opinion is about this.

the example you gave isn't really an advanced concept, it's just something specific to a topic
"advanced concept" is really vague, so can't really point you to a resource with just that
js apis, how syntax/structures work, web/node apis, internals, performance/optimization
these are all very different directions
