Methods whose name ends with "?" return false if the receiver value is nil or false

Currently methods whose name ends with "?" return true only if the receiver is true.

Browser's Element.closest method returns null when no matching element is found.
Using this API in ruby.wasm, we get the following.

if event[:target].closest(selectors) != JS::Null
  # do something
end

If meethods whose name ends with "?" return false if the receiver value is nil or false, we get the following.

if event[:target].closest?(selectors) 
  # do something
end

This would violate the existing ruby.wasm API design policy of not hiding JavaScript information as much as possible.
I think it would be easier for Rubyists to use if only nil and false were false as in Ruby.
What do you think?

If you have a good name, it would be good to create a new method that judges loosely.

How about applying JavaScript's Boolean(v) against returned value when calling methods with ??

Your idea is sufficient for my application.
I have implemented it in #443 to try it out.
