I’m trying to understand how a Proc is useful vs. a Method… was able to succesfully pass the proc to a method see image 1… but for image 2 was wondering how to replace the same process without the Proc… seems I am missing something that is obvious…

Line 4 is not a Proc. See line 4 in your previous post.

Like function expressions in JavaScript, we can reassign a new Proc to the variable anytime we wish to alter the code, and do it on the fly. With a defined method we don’t have that luxury. It would mean having to create multiple methods to accomodate our needs and that cannot be done when the program is running.
