People think the MEAN stack (MongoDB, Express.js, AngularJS, and Node.js) is a good idea because it allows for full-stack JavaScript development, meaning that the same language can be used on the front-end and back-end of a web application. This can make development faster and more efficient because developers only need to know one language, and it can also make it easier to transfer data between the front-end and back end. Additionally, the technologies used in the MEAN stack are open-source and actively maintained, which means that they are widely supported and have a large community of developers contributing to them.

As far as web development is concerned, JavaScript frameworks have been most sought after platforms. With every passing day, JavaScript is now gaining more than before acceptance rate among developers. Today it is not only efficient for developing frontend of the application but is equally capable of backend development.

Contrary to the current belief that JavaScript is highly useful for front-end web developers, it has found new areas in back-end development also.
Any application that can be written in JavaScript, will eventually be written in JavaScript.” — Jeff Atwood

The push() method is used for adding one or more elements at the end of an array and returns the new length of the array. In order to add items at beginning of the array unshift() method is used. It can be used with call() or apply() with objects that are similar to arrays. The push method applies the length property to identify pint of inserting the given values. When the length property is not converted into a number 0 is used as index. This considers the possibility of length being nonexistent hence in such scenario length will be created.
