.keys(hash, collection = []) ⇒ Array<Symbol, String>

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Grab all keys at any level of the hash.

{ foo: { bar: { baz: {} } } }

Becomes

:foo, :bar, :bar

Parameters:

  • hash —

    the hash we want to process

  • collection (Array<Symbol, String>) (defaults to: []) —

    the memoized collection of keys

Returns:

  • (Array<Symbol, String>) —

    the keys
