JavaScript How to trace function calls in Marionette trace function calls python,trace function calls c++,trace function

Somewhere in the global scope:

let App =  Backbone.Marionette.Application.extend({});
window.Ext = new App();

Inside Module A:

Ext.vent.trigger('Tracked:Email:send', {
    from_email: tracking_data.sender,
    to_emails: tracking_data.to,
    cc_emails: tracking_data.cc,
    email_id: tracking_data.email_id || '',
    template: tracking_data.template_id || '',
    subject: tracking_data.subject
});

Inside Module B:

Ext.vent.on('all', function (evt_name, params) {
    // something else...
    console.log(params);
}

The object's properties (from_email, to_emails & cc_emails) are undefined when I call console.log in Module B.

I've tried to debug this using console.trace, but the console doesn't show any functions that are involved in changing the object. I've also tried using Object.observe to capture the act of changing the object but no changes are detected.

Can some please teach me some debugging techniques to trace function calls and events in Marionette.

The scenario is:

  1. our codebase is huge.
  2. I'm a new guy at our company so I'm not sure if there are other functions or events that are involved.
  3. I'm the only front end developer right now.
