Polyfills
|
|
</h3>
|
|
|
|
<p>
|
|
A {@link https://remysharp.com/2010/10/08/what-is-a-polyfill polyfill} is a bit
|
|
of code that fills in missing APIs or normalizes variations in APIs. A polyfill
|
|
allows other pieces of code to expect a single API from the underlying browser.
|
|
</p>
|
|
|
|
<p>
|
|
The Shaka Player uses polyfills to modify, rename, or replace various pieces of
|
|
browser functionality. Before instantiating the Player, these polyfills should
|
|
be installed into the JavaScript environment.
|
|
</p>
|
|
|
|
<p>
|
|
Each polyfill has its own class and a static install() method. We suggest that
|
|
you install all polyfills, since the install method will intelligently detect a
|
|
browser's capabilities and only patch APIs which need patching.
|
|
</p>
|
|
|
|
<p>
|
|
Once browsers commonly implement the necessary functionality consistently, some
|
|
polyfills can be removed to reduce the size of the JavaScript code.
|
