javascript - forEach not working when for loop does with an array of objects -

i have array so

var updates = [];

i add stuff array this

updates["func1"] = function () { x += 5 };

when call functions loop works expected

for(var update in updates) {      updates[update](); }

but when use foreach doesn't work!?

updates.foreach(function (update) {      update(); });

foreach works in browser google chrome, doing wrong?

foreach iterates on indexes not on properties. code:

updates["func1"] = "something";

adds property object – incidentally array – not element array. in fact, it's equivalent to:

updates.func1 = "something";

if need hashmap, can use plain object instead:

updates = {};  updates["func1"] = "something";

and iterate using for…in, shouldn't used on arrays

or can use object.keys retrieve properties iterate on them:

object.keys(updates).foreach(function(key) {     console.log(key); });
