-   * Use the `slice` method to create a `reptiles` array with `snake` and `lizard` from the `pets` array.
-   * Console.log the `reptiles` array and run the program.
-   * Now console.log the `pets` array and run the program. Why do you think `snake` and `lizard` are still in the original array?

-      * `forEach` requires a function to be passed into it as its first argument.
-      * Build a function called `addTwo` that can take in num, index, and arr as parameters—`(num, index, arr)`—and returns `num + 2` at each `index` of the `arr`.
