assigning props/functions with for loop vs directly

[Guest]

Say you have X number of objects, and you want to assign a value to their properties, or add an EventListener.

You could list all X number of objects, and set their property values as such ( objectX.property = value )

Of course that'd be silly if X number of objects was 100, or even 10...I'm lazy.

So instead you put X number of objects into an array, and loop through that array adding values to their properties.

I'm simply curious as to what runtime performance difference there would be. Anyone tried anything like this, or care to speculate in theory?

Heh, I've been known to loop for only three objects. It depends on how
much is going on with the various assignments. If they're long/complex
enough, a loop saves typing.

In my experience, runtime performance isn't affected (or if it is, it's
affected a negligible amount). Dynamic assignment is an
author-time/programmer's convenience, and also comes in handy when the
number of objects to be assigned is unknown. Those are the primary benefits
I see.

HAH! I hear that!
