While logical considering the memory and security constraints, the queue approach becomes especially problematic for things like timing events, which, despite a programmer’s intentions, may be forced to fire out of sequence—creating unexpected output or other errors.
This uncertainty can make debugging scripts a laborious process, fraught with
In Chrome, the timeline can be accessed by navigating to View > Developer > Developer Tools, then clicking Timeline and starting a new capture. Accessing the timelines in Safari and IE follows a similar process.
Analyzing scripts with the timeline provides significantly more insight into event queues and browser processes, and can reveal a wealth of subtle interactions or clarify errors that otherwise would take much longer to find and debug.
