The push() method in JavaScript adds one or more elements to the end of an array. This method modifies the original array and returns the new length of the array.
Syntax :
array.push(element1, element2, ..., elementN);
*Example 1.: *
const fruits = ["Apple", "Banana"];
fruits.push("Orange", "Mango");
console.log(fruits); // Output: ["Apple", "Banana", "Orange", "Mango"]
*Example 2.: *
