">Fatal warnings are a ticking time bomb (via chromatic)</a>
<br />
<p style="font-size: 16px">
You might know that warnings can be changed to throw exceptions in a lexical scope. What you might not know is that some modules, that turn on 'use strict' - for example Moo, will also change the warnings into exceptions. I don't think the fear created in the title is warranted, but it is better to remind ourselves of this behavior. In any case, you can comment on the article to voice <b>your</b> frustration.
