Ruby is a versatile programming language that has many features that make it stand out from other languages. One of these features is the syntax for functions. Functions are defined in a similar way to methods in other languages, but there are some key differences. One of the most important differences is that functions can be called from anywhere in your code, as opposed to methods which must be called from within a class or module. This makes functions more versatile and allows you to write code more easily modularly. Another difference between functions and methods is that functions can take any number of arguments, whereas methods can only take one argument. This means you can use functions to perform more complex tasks than you could with methods alone. Overall, Ruby’s function syntax is very powerful and allows you to write code in a more concise manner than other languages. If you’re looking for a versatile language with some unique features, then Ruby may be the right choice for you! ..
Function Syntax
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.
The return statement also can be shortened for very simple functions into a single line
You can simplify the function further. The last expression that is evaluated is automatically returned by the method. For example:
This would return the same value as the prior functions.
