Those are just like Moose MethodModifiers, just for JavaScript, nice!

Just be careful not to add too much overhead. The example code is applied to the form field base class, meaning it is executed every time any type of form field is created, so adding too much code to that could impact performance greatly.

Nothing really….same thing, different syntax.

Great suggestion, I will have to start switching a lot of my extended code over to intercept & sequence instead. Thank you for taking the time to write this article up.

What is the difference with the createInterceptor (the built-in function extenstion from extJs?

Sequence is the opposite of intercept...well, I should say it does the same thing as Intercept, but instead of executing before the method defined, it executes after the method defined.

Execution order:
-> Intercept
-> Method (ie: initComponent)
-> Sequence

(Thanks, I have updated the post with this additional info)

Thanks for the intercept explanation. So what is sequence ?

You’ll just have to wait for the Override blog post to find that answer

Thanks for the praises. I appreciate it.
