Ruby Null-Conditional operator [duplicate]

Question

C# has a null-conditional operator that works like this

SomeObject?.SomeParam

If SomeObject is null, then the result of that expression will be null rather than throwing a null reference exception. Does something like this exist in Ruby?

Answer 1

Yes. Use &. to call a method.

some_value&.some_method

If some_value is nil, then some_method will not be executed, and the return value of the expression will be nil. Otherwise, some_method will be called as with when called with ..
