Is there any performance issues if I apply a client script to 5 different record types? Or is it better to make a script record for each record type I am deploying to?

q1: is worth the time to do the same script 5 times? q2: the future changes to the script should be the same for every record type? hope this help. keep in mind that you could do your own custom modules in case you wanna encapsulate some functionalities

@Carlos J. Garcia Thanx that was my initial thought just wanted to confirm
