Ruby single and double quotes

Question

I\'ve recently been coding in Ruby and have come from Python, where single and double quotes made no difference to how the code worked as far as I know.

I moved to R

Answer 1

You should read the Literals section of the official Ruby documentation.

It is very concise, so you need to read carefully. But it explains the difference between double-quoted and single-quoted strings, and how they are equivalent to %Q/.../ and %q/.../ respectively.
