Chrome: timeouts/interval suspended in background tabs?

Question

I was testing the accuracy of setTimeout using this test. Now I noticed that (as expected) setTimeout is not very accurate but for most appliances

Answer 1

I recently asked about this and it is behaviour by design. When a tab is inactive, only at a maximum of once per second the function is called. Here is the code change.

Perhaps this will help: How can I make setInterval also work when a tab is inactive in Chrome?

TL;DR: use Web Workers.
