arraypush

Arraypush is a fundamental operation in programming that adds elements to the end of an array data structure. This method increases the length of the array by the number of elements added and returns the new length of the array after the operation. The push operation is commonly used in various programming languages including JavaScript, PHP, Python, and others, though the syntax may vary slightly between languages.

In JavaScript, the syntax is array.push(element1, element2, ..., elementN), where element1 through elementN are the elements to be added to the end of the array. For example, if we have an array let fruits = ['apple', 'banana'], then fruits.push('orange') would result in ['apple', 'banana', 'orange'].

The push operation is efficient with a time complexity of O(1) for adding a single element, making it suitable for scenarios where elements need to be frequently added to the end of a collection. It is widely used in implementing data structures like stacks, where elements are added and removed from the same end (last-in, first-out principle).
