Treehouse Console vs. IRB

Why do we have to go into the IRB from the Treehouse workspace's Console to work with Ruby?

Do we need to have both platforms to work with Ruby? And are there instances where we can work with only the IRB?

The Treehouse console is literally the same thing as opening a terminal window on Mac/Linux. You aren't supposed to use languages like Ruby directly in it. You need to run an interpreter to understand the code you're writing. For Ruby, you can use IRB. It's a Ruby interpreter which makes it possible to test out and run Ruby code. You can't run Ruby code in the console without using IRB, same as not being able to use Java without using java-repl, or python without ... well python3(is the command). All of these commands provide an interface within the console to be able to use the programming language of your choice. These are mainly used for testing out different pieces of code and logic.
