<p><a target="_blank" href="http://www.ecma-international.org/ecma-262/6.0">ECMAScript 2015
specification</a> adds additional static methods on <code>TypedArray</code>
subclasses (<code>Int8Array</code>, <code>Float32Array</code>, ...) and instance
methods on their prototype that mirror most <code>Array.prototype</code>
methods.</p>

<h2>TypedArray.from ( items [ , mapfn [ , thisArg ] ] ) <a target="_blank" href="http://www.ecma-international.org/ecma-262/6.0/#sec-typedarrayfrom">#</a></h2>
<p>
The <code>TypedArray.from()</code> method creates a new way to make
<code>TypedArrays</code> based on existing iterable or Array-like objects,
analogous to <a href="https://googlechrome.github.io/samples/array-methods-es6"><code>Array.from</code></a>.

<h2>TypedArray.of ( ...items ) <a target="_blank" href="http://www.ecma-international.org/ecma-262/6.0/#sec-%typedarray%.of">#</a></h2>
<p>
The <code>TypedArray.of()</code> method is almost the same as <a href="https://googlechrome.github.io/samples/array-methods-es6"><code>Array.of()</code></a>.
</p>
