This section provides descriptions on string literals and a tutorial example on how to use them in JavaScript source code.

To provide values of strings in JavaScript source code, you need to use string value literals following these rules:

1. String literals are sequences of Unicode characters.

2. String literals must be enclosed in single quotes ('...') or double quotes ("...").

3. Several characters must be preceded with the escaping character, backslash (\): \b, \f, \n, \r, \t, \v, \', \", and \\.

4. Latin-1 characters can be presented as hexadecimal escape sequences. For example, \xA9 represents the copyright symbol.

5. Unicode characters can be presented as Unicode escape sequences. For example, \u4E16 represents a Chinese character.

Here is a JavaScript tutorial example that shows you how to use string literals in JavaScript source code:

<body>

<script type="text/javascript">
   document.write("Hello World!");
   document.write('\n');

   document.write('Herong\'s Tutorial');
   document.write('\n');

   document.write("Double quote (\")");
   document.write('\n');

   document.write("Copyright \xA9 2008.");
   document.write('\n');

   document.write("\u4E16\u754C\u4F60\u597D\uFF01");
   document.write('\n');
</script>
</pre>
</body>
</html>

The output of this sample JavaScript is: 

Hello World!

Double quote (")
