A string (or a text string) is a series of characters like “John Doe”.
Strings are written with quotes. You can use single or double quotes:
var carName = "Volvo XC60";   // Using double quotes var carName = 'Volvo XC60';   // Using single quots
You can use quotes inside a string, as long as they don’t match the quotes surrounding the string:
var answer = "It's alright";             // Single quote inside double quotes var answer = "He is called 'Johnny'";    // Single quotes inside double quotes var answer = 'He is called "Johnny"';    // Double quotes inside single quotes
You will learn more about strings later in this tutorial.
