$arr vs $names

Hello Hampton Paulk,

My question is related to the argument you've used in the above video. for ex:-

You've used $arr as an argument for array.

but for storing the names you've used different variable $names ?? why

I mean is it necessary to pass the $arr for array ?? or their is some other trick which i am not understanding ??

Please Help.

Best Regards, Rohit

variables can be anything(pretty much) that you want to use. using "arr" is just easier to understand that it is an array that you are working with. Using "names" as a variable is pretty explicit. It helps you to not guess what the variable is referencing.... it could be "x" or "y" or anything really, but using those as variable names will make you guess what they are days or months down the road... Hope this helps...
