Transcript from the "What are Variables?" Lesson
[00:01:22] Now because I'm sort of old I kind of think about this like speed dial on a phone. Which is the thing that we don't really have anymore because [LAUGH] you we don't need to anymore, but it used to be that you could have a few different speed dial numbers on your landline and you could press one of them like the Simpsons, I guess did.
[00:01:43] And get a certain number just dialed for you. Nowadays maybe this is more like adding a contact to your contact book or contact, I don't know app or whatever it is, you're iCloud Drive I don't know [LAUGH]. I think about variables as sort of @!a new contact in our address book that is associated with a particular phone number so like 555555, 5555, I can save that number as a contact in my contact book.
[00:02:16] And I could maybe change the name of that contact or maybe my contact changed their phone number and got a new number. What they're not going to do is kind of edit their number a little bit or something like that. So what we really have here is an association between the name that I have this person saved as in my phone and the phone number which is what my phone is actually gonna dial when I try to dial this person using their name and my phone.
[00:02:44] When I say hey Siri I don't have an iPhone. But let's say I did, hey Siri, call Stephen. That's going to dial a certain number that is associated with Stephen in my address book. So, this is kind of a mental picture that I use as opposed to the container picture.
[00:03:01] Is more of a pointer or an address book kind of picture.
