-Why pay a fortune teller when you can just program your fortune yourself?

-1. Create four arrays, `numKids`, `partnerNames`, `locations` and `jobTitles`. 
-   Give each array five random values that have to do with the name of 
-   the variable.
-
-2. Complete the function `selectRandomly`. This function should take an array 
-   as a parameter and return a randomly selected element as its return value.

-3. Complete the function named `tellFortune` as follows:
-
-   - It should take four arguments (in the order listed): 
-     * the array with the options for the number of children, 
-     * the array with the options for the partner's name, 
-     * the array with the options for the geographic location and 
-     * the array with the options for the job title.
-   - It should use the `selectRandomly` function to randomly select values from 
-     the arrays.
-   - It should return a string: "You will be a `jobTitle` in `location`, 
-    married to `partnerName` with `numKids` kids."
-
-4. Call the function three times, passing the arrays as arguments. Use `
-   console.log` to display the results.
-
