<h2 id="Description">Description</h2>

<p>The <code><strong>Intl.Locale</strong></code> object was created to allow for easier manipulation of Unicode locales. Unicode represents locales with a string, called a <em>locale identifier</em>. The locale identifier consists of a <em>language identifier</em> and <em>extension tags</em>. Language identifiers are the core of the locale, consisting of <em>language</em>, <em>script</em>, and <em>region subtags</em>. Additional information about the locale is stored in the optional <em>extension tags</em>. Extension tags hold information about locale aspects such as calendar type, clock type, and numbering system type.</p>

<p>Traditionally, the Intl API used strings to represent locales, just as Unicode does. This is a simple and lightweight solution that works well. Adding a Locale class, however, adds ease of parsing and manipulating the language, script, and region, as well as extension tags.</p>
