javascript - Creating a "delay" function in JS? -

i've been reading settimeout , other such timers. i'm wondering if it's possible work custom function need this:

//code delay(time); //more code 

is possible?

update: ok, kind of it. if isn't reasonably possible, how go delaying loop after first time. want run upon execution delay on each iteration afterward.

new update: figure since initial thought fell through, might easier show code have.

function autofarm (clickevent){  var farmtargets = [             "6_300_1",             "6_300_3",             "6_300_4",             "6_300_5",             "6_300_7"];   settimeout(function() {  $.each (farmtargets, function(index, target){          var extradata = '{"end_pos":"' + target + '","purpose":0,"upshift":1,"bring_res":{"0":0,"2":0,"1":0},"bring_ship":{"1":25,"11":0},"rate":100,"start_pos":"6_300_2"}';  var finaldata = basedatadora + extradata + "&type=1";   settimeout(function(){     (i = 0; < farmtargets.length; i++){         postrequest(sendfleeturl + getsign(extradata). finaldata, function(json){                        });                  }         }, 15000);   });//end each loop }, 1320000);     }//end autofarm 

basically, should execute , run loop 5 times on first array element 15 seconds apart. 22 minutes later move next set , repeat entire array.

you can achieve along lines generators. idea continuation passing style (callback hell) can flattened. generator uses yield keyword pause function, until callback resumes calling next method:

var async = function(gen) {   var g = gen()   function next(x) {     var cur = g.next(x)     if (cur.done) {       return cur.value     }     cur.value(next)   }   next() }  var delay = function(time) {   return function(f) {     settimeout(f, time)   } }  async(function* () {   console.log('before')   yield delay(1000) // waits 1 second   console.log('middle')   yield delay(1000) // waits 1 second   console.log('after') }) 

in cps read like:

console.log('before') settimeout(function() {   console.log('middle')   settimeout(function() {     console.log('after')   }, 1000) }, 1000) 

this works in chrome, firefox , iojs today.
