What is the syntax for representing human speech in JavaScript?

We use strings, for instance 'To be or not to be', 'Ophelia', "It's time to go!".

Strings are enclosed either in single quotes or double quotes. Double quotes are useful if you need to include single quotes or apostrophes in the string itself.
