Hi all. I'm currently learning js and I have a question. In js, is it possible to see the source code of objects such as Window.
When I was learning java, you could open the library there and see everything about everything, and it's very cool to understand. Is there no such thing in js?

Every modern browser has developer tools.
For example: console.log(window) will print information about the window object to the browser console.

Well, in principle, you can open the source of V8 and see how it is implemented, but I do not advise. It's best to read the specs.
