What's this piece of code going to display in the console?

[4.0, 8.0, 15.0, 16.0, 23.0, 42.0][4, 8, 15, 16, 23, 42][2.0, 4.0, 7.5, 8.0, 11.5, 21.0]NaN

Perfect! This while loop simply doubles every number in numbers, an array with decimal values.

Yikes! This while loop simply doubles every number in numbers, an array with decimal values.
