I am trying to build "event" queue similar to this: https://stackoverflow.com/a/24932757/6385482
but without using any libraries (e.g. jQuery, Bluebird, Q)
Example: I have an array
var event = [func1, func2, func3];
...and i want to implement function called 'each' which itaretes 'event' and calls async function sequentially.
Sorry for my English.
Thank you for your help.
thanks for your reply. Functions are already async, and I need to call func2 after func1 is done (they can't overlap)... I wrote my this function using Bluebird, here is an example:
var Bluebird = Promise.noConflict();
var items = [
function () {
return new Bluebird(function (resolve, reject) {
console.log("promise1 pending");
setTimeout(function () {
console.log("promise1 fulfilled");
resolve();
}, 1000)
})
},
function () {
return new Bluebird(function (resolve, reject) {
console.log("promise2 pending");
setTimeout(function () {
console.log("promise2 fulfilled");
resolve();
}, 500)
})
},
];
Bluebird.each(items, function (item, i) {
return item();
});
This does exactly what I need, first calls "promise1 pending", then "promise1 fulfilled", then "promise2 pending" and "promise2 fulfilled"...
I tried to write this function with native Prosmises, but I couldn't figure out how.
Thank you for your help
func1,func2, andfunc3? Are they already async, or are they sync and needing a wrapper? Do you want to wait to callfunc2untilfunc1's work is complete, or can they overlap? What have you looked at so far, what's worked, what hasn't worked?
