// Demo

// A simple demo of how to use the following PubSub module
// DO NOT USE ANONYMOUS FUNCTIONS AS YOU WILL BE UNABLE TO UNSUBSCRIBE

function fireFirst() {
    console.log('fireFirst: %o', arguments);
}

function fireSecond(_, arg1) { // _ = event, therefore this can be ignored
    console.log('fireSecond: %o', arguments);
    console.log('Arguments: %s', arg1);
}

// Subscribe to an event and bind a callback for each by passing a function reference
$.subscribe('search/twitter', fireFirst);
$.subscribe('search/twitter', fireSecond);

// Publish the event
$.publish('search/twitter', ['Example arg1', 'Example arg2']); // Must be an array of arguments

// Look in the browser's console

// Destroy the event only for the second function by passing the event name and the function reference i.e. fireSecond (no parentheses)
$.unsubscribe('search/twitter', fireSecond);

// Publish the event
// Notice how there is only one console.log() displayed, which is for the fireFirst() function
$.publish('search/twitter', ['Example arg1', 'Example arg2']); // Must be an array of arguments
