There are three string quote options in JavaScript:
"Hello"'Hello'`Hello`Double and single quotes behave identically. Backticks allow code to be embedded into a string via ${...} wrapping.
var str = "Hello World";
var str2 = 'Hola Mundo';
var str3 = `English: ${str}, Spanish: ${str2}`
var str4 = `${1 + 2}`; // '3'
Escape sequences:
'\xA9''\u00A9' or '\uP00A9'
