#2867 — Using underscors or camel case for variables and functions (def)

I thought you couldn't use camel words in Ruby instead you should use
underscores but I just tried it and it works.

Here is the code I tried.

class Calculator
  def addIt num1,num2
   _num = num1 + num2
    puts _num.to_s
 end
  def subIt num1,num2
   _num = num1 - num2
    puts _num.to_s
 end

end

add = Calculator.new
sub = Calculator.new

add.addIt(5,5)
sub.subIt(5,2)

Is this valid in Ruby or it works but is not semantically correct?

Thanks

It's a style convention, not something Ruby's parser would enforce.

Though the folk I have met,
(Ah, how soon!) they forget
When I've moved on to some other place,
There may be one or two,
When I've played and passed through,
Who'll remember my song or my face.

I probably misunderstood this and honestly I don't remember where I read 
that.

Thanks a lot for the clarification!

In fact, camel case is recommended for names of constants:

class MyClass  #camel case for constants
end

def my_method  #snake case
end

my_var = 1     #snake case
