Summary
Var-oom! Variables are the key to making coding more efficient. These handy labels help programmers store important bits of information in coding languages like JavaScript. Declare a value for the variable; then access it anytime just by typing the variable's name. No more repeating long strings of text! You can name variables anything you want, and add, remove, or modify values to suit your needs. But it's not a total free-for-all. As with all coding, a bug can freeze a program in its tracks if instructions aren't written in the right order. So follow Moby and computer whiz Nat as they walk through all the steps, from declaring to initializing to debugging!
