Javascript is one of the most popular programming languages for developing real-time web applications. With the evolution of technology, the demand for real-time web applications has increased significantly, making Javascript an indispensable tool for developers.
To develop real-time web applications with Javascript, it is necessary to use some specific tools and technologies, such as Node.js, Socket.io and WebSockets.
Node.js is a Javascript application development platform that uses Google Chrome's V8 engine. It allows Javascript to run outside the browser, making it possible to create real-time web servers.
Socket.io is a Javascript library that enables real-time bidirectional communication between the server and the client. It uses WebSockets, but is also capable of using other transport mechanisms such as AJAX and JSONP.
WebSockets is a real-time communication protocol that allows data to be exchanged between the server and the client in real-time. They are supported by major browsers such as Google Chrome, Mozilla Firefox, Safari and Microsoft Edge.
