Just try to get to modular JavaScript and pick a framework. You go learn JavaScript forever.

when you're good at something, you would know.

Just keep learning until you see a JavaScript problem or script and it's nothing to you, then you're good

You will always keep learning JavaScript, but when you learn what @operation moses listed above and know how to use them to solve real problems and built applications without having to run to google every step of the way, then you are proficient with the language.
N/B Every programmer googles stuff, but as you progress you no longer have to google how to do basic stuff because you have become proficient.

That may be a tough one to answer but off my head you have understand the following:
1. The execution environment of javascript (browser or server) and the javascript engine running in each
2. The concept of variables and constants, the concept of assignment by value and by reference
3. The eight datatypes in js (numbers, string, boolean, object, null, symbol, undefined, bigint)
4. javascript language construct and statement syntax
5. Statement control and looping
6. Variable scope
7. Functions, objects and object data type like array
8. The new ECMAscript 2016 and the changes it brought to javascript
9. The concept of class object in javascript

When you are through with the above fundamental knowledge, you can start learning javascript as it relates to document object modelling (DOM) before you move to advance topic like closure, promise etc
