There is. That's Service Worker :)

I'm not joking. Service Workers came out of a series of meetings called 
"Fixing AppCache". The initial idea hadn't been to come up with a new 
API, it really was to figure out a way to take the existing AppCache and 
somehow make it tick. But it surfaced during that work that that was 
going to be pretty hard, if doable. Service Worker was put forward as a 
proposal to make it possible to support the AppCache use cases better, 
but in script. In fact one of the first things that happened when we had 
the basics of the API hashed out was that I used those to write an exact 
AppCache replacement in that API.

The downside of SW is that they aren't declarative, which is what you'd 
like for a lot of cases where scripting seems overkill. I can imagine 
that once we do have SW sufficiently operational (and it does seem to be 
making good progress there) then a useful declarative subset can be made 
available (and shimmed). But we're definitely not at that step yet.

JavaScript is fun :)
