No public or private keywords
Hey, I think you have mistaken.
The private keyword is used to hide a method or a property in a class from. To do this in js, you can use

class Hello {
    _private_function(){}
}
Enter fullscreen mode Exit fullscreen mode

Regarding new proposal: why to use # instead of private keyword for the private members? Or am I missing something here?

FAQ:

This sort of declaration is what other languages use (notably Java), and implies that access would be done with this.x. Assuming that isn't the case (see below), in JavaScript this would silently create or access a public field, rather than throwing an error. This is a major potential source of bugs or invisibly making public fields which were intended to be private
