Events – why something.changed instead of something.on(“changed”, ….

Whenever I was using custom events there were:

something.on("changed", function myonchange() {
    do_something_here
});

However, now I start to use better way:

something.changed(function myonchange() {
    do_something_here
});

The benefits of this change are:

• The list of events can be seen in the debugger.
• Events can be copied from one object to another.
• Several events can be aggregated into one.
