Right away, we begin by checking to see if the user gave us a string in the form of a command line argument:
if ARGV.length >= 1
If not, we exit the program
Otherwise, we store the command line argument that the user passed into a string:
else string = ARGV puts string.reverse end
Then, we reverse the string using the built-in method of the string class and print the result onto the screen.
As we can see, our solution is very brief. That's because we're using a high-level language that offers many different tools, so we can concentrate on building our application instead of worrying about implementation details.
If you have Ruby installed on your machine, you can run the following command:
ruby reverse-string.rb SomeStringHere
Alternatively, websites like REPL allow you to run code from several programming languages in your browser. Feel free to leverage one of those!
