Rename the draw function

[aleclarson]

To me, “drawing” in this context implies the array will be mutated (like how a deck of cards depletes as you draw from it).

Possible new names:

1. randomItem
2. randomElement
3. randomValue

What if we want to have similar functions for objects? randomKey and randomValue fit object functions as well.

I see two options:

1. Without polymorphism: randomKey and randomValue for objects, randomElement for arrays
2. With polymorphism: randomKey and randomValue for both arrays and objects
