arrays

fruits.forEach(function(item, index, array) {
console.log(item, index);
});

var array1 = [1, 2, 3];

console.log(array1.includes(2));
// expected output: true

var months = ['Jan', 'March', 'April', 'June'];
months.splice(1, 0, 'Feb');
// inserts at index 1
console.log(months);
// expected output: Array ['Jan', 'Feb', 'March', 'April', 'June']
