NodeJS is used to develop applications that make extensive use of the ability to run JavaScript both on a client as well as the server. It uses a single threaded event loop to handle requests. The non-blocking I/O eliminates the need for multi-threading. As a result, it is highly scalable and the load intensity in the server is not as much as PHP. Before NodeJS, Javascript was only used for client-side development. Separate devs had to be hired for backend and frontend. With the inception of NodeJS, full-stack Javascript was finally possible. One can use NodeJS in the front end, back end as well as in mobile development. Juego Studios is a Node.js web & mobile app service provider developing user-friendly apps for clients.
