This is a Ruby tree! It shows every object from the Ruby Programming Language in a tree format.

any? 

        # Hash.any?

(from ruby core)
---
    hash.any? -> true or false
    hash.any?(object) -> true or false
    hash.any? {|key, value| ... } -> true or false

---

Returns `true` if any element satisfies a given criterion; `false`
otherwise.

With no argument and no block, returns `true` if `self` is non-empty;
`false` if empty.

With argument `object` and no block, returns `true` if for any key `key`
`h.assoc(key) == object`:
    h = {foo: 0, bar: 1, baz: 2}
    h.any?([:bar, 1]) # => true
    h.any?([:bar, 0]) # => false
    h.any?([:baz, 1]) # => false

With no argument and a block, calls the block with each key-value pair;
returns `true` if the block returns any truthy value, `false` otherwise:
    h = {foo: 0, bar: 1, baz: 2}
    h.any? {|key, value| value < 3 } # => true
    h.any? {|key, value| value > 3 } # => false
