title: How to read Chrome profiler
body: <p>I am using the Chrome javascript profiler to try to optimize a very compute heavy feature of my application.  The bottom up view refers over and over to what seems to be a function called &quot;value&quot;.  I'm struggling to understand what this is. When I click the link to code line number, it doesn't go anywhere.  main.app.js is a huge file of course.  We use underscore pretty heavily so it could potentially be the .value() you must call at the end of any chained sequence?  In general I find the profiler very hard to use.</p>
