why are some javascript errors recoverable and some not
<p>I'm using a lot of javascript on my site and of course sometimes things go wrong when building code and bugs appear. Sometimes the page runs into a bug and all scripts stop working. This is especially true if a bug is triggered during page load. And sometimes some bugs don't seem to stop the page from running more scripts.</p>

<p>And then sometimes I look at some pages on the web, press F12 and I see that the page has 5-10 javascript bugs and yet just keeps working seemingly fine.</p>

<p>What makes some javascript error fatal and others recoverable?</p>

<p>Thanks.</p>
