queryselectorAll usage
<p>I am currently upating my organisations custom JS library and one thing I am looking to introduce is querySelectorAll.</p>

<p>Looking at compatibility it will run in modern browser and for older browsers I will use feature detection:</p>

<pre><code>if (document.querySelectorAll) {
            var nodes = context.querySelectorAll(queryValue);
} else {
    var nodes = context.getElementsByTagName(queryValue);
}
</code></pre>

<p>Are there any considerations that I should be aware of when using this method or is it good for production?</p>

<p>All opinions valued</p>
