Do your Jasmine tests (or anything else) seem to lock up when they aren’t the active tab in your browser?
Unfortunately, your new and modern browser is to blame. There are a few workarounds, but none of them are ideal in my opinion.
You might also be surprised to find out that HTML5 specifies a minimum of 4ms delay for
This is the easiest solution, but it’s often less convenient to switch between browser windows when you want to just switch between tabs in the same window.
The accepted answer at this StackOverflow question demonstrates how you can figure out “where your animation is supposed to be” and just jump ahead. This workaround probably doesn’t apply if you have logic beyond visuals that depend on somewhat accurate timing.
Microsoft recommends using the
setImmediate function as a replacement for
setTimeout with a delay of 0.
But Mozilla has this to say about
This method is currently only proposed, is not expected to become standard, and is only implemented by recent builds of Internet Explorer.
On a side note, the Microsoft page has a lovely visualization of quicksort.
Another not-yet-standardized function,
requestAnimationFrame seems best suited for animations, not for precise timing.
I’m being somewhat facetious here, but Chrome and Firefox both have hardcoded constants for the interval limit. Without looking through the rest of the source code, I can’t conclusively say for either browser that there is no simple way to add support for overriding the inactive tab’s clamp value.
I saw one or two mentions about Firefox having an option to overwrite the minimum timeout limit, but since I’m not able to find those links again or any further information about those options, I’m led to believe that Firefox also does not let you override that one second minimum limit.
