Whether it's written in Ruby or another language, almost all software needs to work with text. Programming languages represent text in the form of strings. A string is just a series of text characters. All languages let you work with strings, but Ruby makes it especially convenient.
- A string is a series of text characters
- A string can be surrounded by single or double-quotes.
'A string'
"Also a string"
- Almost all characters within string surrounded by single quotes appear as they are typed:
puts 'I #{represent} "characters" verbatim.'
- Some punctuation marks within double-quoted strings are interpreted specially:
puts "I make some substitutions: #{2 + 4}"
