I recently starting learning JS so a beginner level answer would be great! Thanks. 

function contains(arr, item) {
   // check to see if item is inside of arr
   // return true if it is, otherwise return false

}

    [.includes()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/includes) and [.find()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/find) – Mohammad Usman Apr 05 '18 at 13:01

What about something like this?

const arr = [1,2,3];
const el = 2;
console.log(arr.includes(el)) // true
