Exercise 1

Create a new project directory for today's exercises.
Create a new javascript file in the project directory
- In this file:
  - Create a module that will take an array of numbers and a number. The module should return the the numbers before and after the first instance of the number in the array.
  - Example:
    - Given 45 and [62,89,56,45,12,91,81], [56, 12] would be returned
    - Given 62, [81, 89] would be returned
    - Given 81, [91, 62] would be returned
Create another file that calls the module with an array of numbers and a single number and logs the answers to the console.
