Can someone help me understand how to properly print the items in the q after all results are pushed in this program?
function asyncAdd(a,b,callback) {
setTimeout(function() {
return callback(a+b);
},0);
}
var q = [];
var ctr = 0;
for (var i=0; i<9; i++) {
(function(i) {
var res = asyncAdd(i, 0, printRes);
q.push(res);
})(i);
}
function done(q) {
console.log("done"+q);
}
function printRes(res) {
return res;
}
Take a look at my updated code snippet:
function asyncMultiply(x, y, callback) {
callback(x * y);
}
var products = [];
var count = 0;
var limit = 10;
for (var j = 1; j <= limit; j++) {
asyncMultiply(j, 2, displayResult);
}
function finish(products) {
console.log("All computations completed: " + products);
}
function displayResult(result) {
products.push(result);
if (products.length === limit)
finish(products);
}
