String concatenation vs. interpolation in Ruby

Question

I am just starting to learn Ruby (first time programming), and have a basic syntactical question with regards to variables, and various ways of writing code.

@user1181898 - IMHO, it's because it's easier to see what's happening. To @Phrogz's point, string interpolation automatically calls the to_s for you. As a beginner, you need to see what's happening "under the hood" so that you learn the concept as opposed to just learning by rote.

Think of it like learning mathematics. You learn the "long" way in order to understand the concepts so that you can take shortcuts once you actually know what you are doing. I speak from experience b/c I'm not that advanced in Ruby yet, but I've made enough mistakes to advise people on what not to do. Hope this helps.
