12,842 PointsOverwriting Arrays: Is it really this super easy?
Jason seemed to overwrite the array that he had already created here with the new one:
grocery_list = ["milk", "eggs", "bread", 1, 2, 3]
=> ["milk", "eggs", "bread", 1, 2, 3]
grocery_list = %w (milk eggs bread)
=> ["milk", "eggs", "bread"]
Is the array with the grocery list and numbers being overwritten with the other array? If not, what's happening? Are there now 2 arrays with the same name: grocery_list ?
