Can JavaScript function execution be interrupted?

Question

Having an object to store data.

var store = {
    elements: [],
    eventsEnabled: true,
    addElement: function(element) {
        this.elements.push(eleme         


        

Answer 1

Would it not be more sensible to pass the eventsEnabled in as a parameter to the addElement method?

var store = {
    elements: [],
    addElement: function(element,eventsEnabled) {
        this.elements.push(element);
        if (eventsEnabled) {
            // Code that triggers event, calls handlers... whatever
        }
    }
};

First:

setInterval(function() {
    store.addElement('hello',false);
}, 12000);

Second:

setInterval(function() {
    store.addElement('bye',true);
}, 12000);
