The includes() method checks if an array, which is a list of items in Array, contains a certain value. It gives back true if the value is there, and false if it isn't.

const fruits = ['orange', 'apple', 'watermelon'];



console.log(fruits.includes('orange'));

// Expected output: true



console.log(fruits.includes('banana'));

// Expected output: false
