    // Some and Every Checks
    // Array.prototype.some() // is at least one person 19 or older?
    // Array.prototype.every() // is everyone 19 or older?

    // Array.prototype.find()
    // Find is like filter, but instead returns just the one you are looking for
    // find the comment with the ID of 823423

    // Array.prototype.findIndex()
    // Find the comment with this ID
    // delete the comment with the ID of 823423
