“儿童”在Chrome Devtools中意味着什么？

Question

Since the first time I saw this "child" note, I can't understand: what does that mean?

Answer 1

It's the "type" of the object that is somehow derived by the console API. Often it seems to be the name of the constructor function that created the object. Example:

The console API and output are not standardized, so environments can do whatever they want. It's not a feature of JavaScript and therefore not really relevant for writing your code.

I can only imagine the purpose is that you can more quickly recognize the "type" of the object when inspecting an object.
