I know:
- to declare variables and modify them afterwards unless it's const.
-code functions and arrow-functions
-i know most useful methods for strings, numbers, arrays.
-i know how to create an object manually or from a constructor.
-i know how to create classes with constructors and prototypes
-i know how to manipulate, create or remove DOM objects.
-I know how to use event listeners
-i know how to use intervals and timeouts
-i know how to use static methods.
-i know how to use Math. methods.
-i have some experience in canvas animation.
I think this makes at least 90% of what I know.

— What dont you understand about async await?

— If I'm working just on front end is there any situation that I can use asynchronous function? Or is it just with a server?

— Sure e.g when you fetch something

— So I ment offline mode, is there a use for it when you want to wait for a reaction after event listener for example

— Or is it just for online stuff

— You can do fetch('text.txt')
.then(res=>res.txt())
.then(data=>data)
.catch(err=>err)
