To understand the practical usage of Node.js in industry, we need to have a better understanding of network applications since the platform is explicitly used to design them. Network applications run on host A and provide a mode of communication to another application or tool running on host B. So more or less, it acts as a very well versed mode of communication between two runtime applications based on different hosts.
When developing any application, one of the primary concerns of any developer is to make it shift in usage and memory. For doing that, the application should not be running all the time. I mean it should only run when required by the user and should be very time bound. In technical terms, we call a platform running on such constraints a ‘runtime platform’ and it has become the primary choice for developers nowadays. You must be asking yourself ‘why Node.js?’ Well, the answer is relatively simple. Because it is an event driven platform and is one of the swiftest platforms, developers could use to develop a variety of network applications. Another crucial reason as to why developers prefer Node.js is because it processes and outputs data in segments and never buffers – that’s what every developer and client want!
