.includes(value, fromIndex)

Determines whether the array contains a certain value among its entries. The method can start the search at a specified index.

Examples:

let fruits = ['apple', 'banana', 'mango'];
let includesMango = fruits.includes('mango');
console.log(includesMango); // true

let includesGrape = fruits.includes('grape');
console.log(includesGrape); // false

const fruits = ['apple', 'banana', 'mango', 'orange', 'banana', 'peach'];

// Search for 'banana' starting from index 2
const result = fruits.includes('banana', 2);

console.log(result); // Output: true

// Search for 'banana' starting from index 3
const result2 = fruits.includes('banana', 3);

console.log(result2); // Output: true

// Search for 'banana' starting from index 4
const result3 = fruits.includes('banana', 5);

console.log(result3); // Output: false
