How can you use = methods in Ruby?

Question

ruby

I'm learning Ruby, after C++, I don't understand the following method=, is it a call to the method method and the value is immediately assigned to the object? or how to interpret it?

Answer 1

Yes, this is a setter, quite simply :)
Ruby allows you to use some characters in method names.
Therefore, there are valid?, select! methods.
object.value = 10 is the same as object.value=(10), which in C++ would be object.setValue(10)

Answer 2

This is a setter. Ruby doesn't have public variables. Only getters, setters and internal variables.
