javascript - any performance benefits from passing work to background.js -


i have chrome packaged app have made using polymer paper-elements. uses html5 audio tag stream music online service. issue when app grabs results server , parses array while playing. music stop few milliseconds. (a few seconds on lowend chromebooks) have tried use polymers async method delay work til next available microtask. helps causes undesirable things happen in interface. (content shouldn't displayed shown until async method executed)

currently have nothing happening in background.js file. happening in main.js file or within custom element.

would see performance gain using message passing push of work when parsing response background.js file?

example of work appears cause pause in audio.

        var = 0;         array.prototype.foreach.call(response.albumlist2.album, function (e) {           // buildobject returns needed data object returned loop other needed data           var obj = this.buildobject(e);           // this.wall array pass core-list display           this.wall.push(obj);           // keep callback executing before array built           = + 1;           if (i === response.albumlist2.album.length) {             this.async(callback);           }         }.bind(this));

in situation callback hides loading spinner.

thanks in advance help.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
