Ruby Function Syntax

[Zool]

I know Ruby language makes easy to create functions to call method in program and also enable reuse of code across multiple programs. I need more information on ruby functions and some example which describe where to use that function.

Example of Ruby Function

def functionname(variable)
   return <value>
end

Your function can store this value and call this value to the function through variable which are declare. Those values can then be returned with the return statement.

[Walby]

Some methods defined in the Kernel module can be called from everywhere, and are to be called like functions. You'd better think twice before redefining these methods.The syntax of Ruby is broadly similar to Perl and Python. Class and method definitions are signaled by keywords. In contrast to Perl, variables are not obligatorily prefixed with a sigil. When used, the sigil changes the semantics of scope of the variable.

This Ruby Function Syntax Example will creates an unnecessary function.

def saybye(name)
  result = "bye, " + name
  return result
end
 
# Let's say bye
puts saybye("Ruby")
puts saybye("Syntax")
