The Ruby language makes it easy to create functions.
Function Syntax
def functionname(variable)
return <value>
end
Examples
Your function can compute values and store them in local variables that are specific to the function. Those values can then be returned with the return statement.
def say_hello(name)
var = “Hello, ” + name
return var
end
The return statement also can be shortened for very simple functions into a single line
def say_hello(name)
return “Hello, ” + name
end
You can simplify the function further. The last expression that is evaluated is automatically returned by the method. For example:
def say_hello(name)
“Hello, ” + name
end
This would return the same value as the prior functions.
To call a function
function param1, param2
or
function(param1,param2)
Example
puts say_hello(“Geek”)
