Ruby Strings

Ruby Strings

Basics:

• Strings are a series of characters 'strung' together between quotes.

• Single or double quotes can be used to create strings in Ruby.

• Ruby does some extra evaluation on strings that are created with double quotes, such as:

  • Escaping characters: \n, \t, \s
  • Using variables and expressions inside: #{variable or expression}

• Strings with single quotes are rendered as they are, without any special considerations.

Examples:

"Hello World"
# is equivalent to:
'Hello World'

"This is line 1.\nAnd this is line 2."
# returns:
This is line 1.
And this is line 2.

name = "Batman"
"Hello, my name is #{name}!"
# returns:
Hello, my name is Batman!

# Note that for single quotes, ruby doesn't take special consideration for variables or backslashes:
'This is your name:\n#{name}'
# returns:
This is your name:\n#{name}
