JavaScript Breakpoint Collection Build status

Find out what part of your code is causing a behavior in the browser. For example, you can pause when the window scroll position is updated or when cookie data is written.

Live Demo

Either use the UI or add breakpoints from the console:

breakpoints.debugScroll()
breakpoints.debugPropertySet(obj, "propertyName", "trace") // trace instead of pausing
breakpoints.debugCookieWrites(function(){ /* whatever */ })
breakpoints.resetLastBreakpoint()
