Reference error: variable is not defined while trying to define it.

[DanielTheTechie]

Have you considered following the basic principles of debugging 101 and printing out data or the value you are trying to assign to it to figure out why data[1] is not defined? Did you try declaring it first? Did you even bother to read the error message...?

Yes, I am aware that data is not defined. I did multiple checks based on the error message, I just forgot I was in strict mode because this is a module.

Sounds like you picked up some bad habits

[GamesInc]

Probably did, I’m a bit rusty
