This could even be more helpful if you can make a tutorial on nested try catch finally statements

How come this. syntax is being used when creating a function at 7:51? We haven't done that before, only in objects.

[@DaveGrayTeachesCode]

You can create functions the traditional way or with arrow functions.

[@__zenon]

@@DaveGrayTeachesCode Hey Dave, thanks for the response. We did that in the earlier lessons; I wasn't actually referring to that. I was refering to eg. this.message in a function, instead of just having a variable inside of function. We only used "this." syntax when working with objects and classes.
Thanks!

homie almost said areola

[@yatin1370]

The Try-Catch-Finally example was awesome!

[@DaveGrayTeachesCode]

Glad to hear that!
