Question

Hey I have a simple loop which iterates a bunch of objects and checks if they match a variable and if they do, I want to remove it from the that list.

But i don’t know how to do it… this is the idea of what I am trying to do :

//my_objects is global (window.my_objects)

for(var i in my_objects){

   if(my_objects[i].value == 100){
       //remove it
    }

}

Is there any option besides creating an array for it ? I could only find delete which only deletes the property which means the object will still be itereated through my loop next time around.

This function is called every X seconds.

Answer 1

Deleting the property from the object like this means that it won’t be in the iteration next time:

for(var i in my_objects){
   if(my_objects[i].value == 100){
       delete my_objects[i];
    }
}

Note: this removes the object in question as a property on my_objects. If there is no other code with a reference to the now removed object, then it will be available for garbage collection and eventually freed.
