Line 901:
A JavaScript string is a sequence of zero or more characters enclosed in either 'single quotes' or "double quotes". Neither form prevents escape sequences: <code>"\n"</code> and <code>'\n'</code> are both strings of length 1. There is no variable interpolation.
Unicode characters can be entered as literals or as 4 character hexadecimal escapes. The following expressions are equivalent:
<lang JavaScript>(function () {
return "αβγδ 中间来点中文 🐫 אבגד"
})();
(function() {
return "\u03b1\u03b2\u03b3\u03b4 \u4e2d\u95f4\u6765\u70b9\u4e2d\u6587 \ud83d\udc2b \u05d0\u05d1\u05d2\u05d3";
})();</lang>
Note in the case of the Emoji character, where more than 4 hexadecimal characters are needed, ES5 requires us to separately write a pair of surrogate halves.
ES6 introduces Unicode code point escapes such as <pre>'\u{2F804}'</pre>allowing direct escaping of code points up to 0x10FFFF.
