JS Activity: Testing for an array item

When an array contains primitive values, you can use the Array.includes() method to test if a value exists within that array.

Instructions

1. Download or fork/clone this Gist into your workspace.
2. Using conditional statements and the Array.includes() method, test if the entered command line value exists in the characterClasses array:

   • If true log the following to the console:

     "[inputted value]" is a valid Character Class!`
     

   • If false log the following to the console:

     "[inputted value]" is NOT a valid Character Class! Please try again.`

const characterClasses = [
  'fighter',
  'wizard',
  'rogue',

];
