Where it reads, in referring to setTimeout and setInterval, that “…those functions don’t work with background pages that are loaded on demand”, does it mean they won’t work in the background script period?. "Execution context" doesn't mean "thread", and until recently Javascript had no support for anything resembling threads. Neither setInterval(), nor the more appropriate setTimeout() return Promises, therefore, awaiting on them is pointless in this context.

One of these interfaces’ most essential methods is. Both setInterval and setTimeout are not guaranteed to be on time, see this section on MDN for more details. A few thoughts: setTimeout et al aren't a bad way to introduce asynchronous programming; whether they need to be introduced in depth to introduce the concept I'm less sure; the title "cooperative async JS" is weird; I know it's not one that I would have used, nor one that evokes anything related to setTimeout et al; while there are a number of use. It returns a handle that you can pass into clearInterval to stop it from firing: var handle = setInterval (drawAll, 20); // When you want to cancel it: clearInterval (handle); handle = 0; // I just do this so I know I've cleared the interval. 0. js"); Note: Once a shared worker is created, any script running in the same origin can obtain a reference to that worker and communicate with it. b);}, 200); } So when a.

As a consequence, the this keyword for the called function is set to the window (or global) object, it is not the same as the this value for the function that called setTimeout. You've posted the definition of getContent, not searchTarget.
