Courses Plus Student 4,356 PointsConverting a basic AJAX program
I'm trying to convert one of the projects in the basic AJAX course. I replaced the XHR requests with fetch and promise all and I get no errors. I'm having trouble, however, displaying the data - rooms full, empty and employees in, out. Any suggestions?

- the data items are arrays of objects, and don't have a "message" property (lines 13 & 14)
- the properties of an array ("for in") are just indexes use the values instead ("for of") (lines 36 & 58)
- the "name" is a property of the item ("property") and not the array ("data") (lines 42 & 64)

Courses Plus Student 4,356 PointsThanks, I'll check it out. The message property does work though displaying the array of objects when I logged to console - lines 13 and 14. Why?
Got it figured out, thanks again!

231,184 PointsAttempting to get a 'message" attribute from an array should give you "undefined". If you see something else, what's the complete code in the callback at that point?
