.push()

.push() adds one or more elements to the end of an array and returns the new length.


Examples:

let fruits = ['apple', 'banana'];
fruits.push('orange');
console.log(fruits); // ['apple', 'banana', 'orange']

fruits.push('mango', 'pear');
console.log(fruits); // ['apple', 'banana', 'orange', 'mango', 'pear']
