How Node.js is Better Server Side Programming Language? JavaScript is the most ubiquitous client-side technology today, but it has gained this worth since the Node.js came to the app development world. WHAT IS NODE.JS? Node.js is a server-side environment and allows node js app development companies to create servers as well as network applications with the help of JavaScript in the history. Developing server using Node.js ensures entire sites can run on a unified JavaScript stack. As a result of this, we can now see client-side software, and the server-side software running in JS. However, it is imperative to understand that it is a development platform, not a framework. Therefore, Express.js and other frameworks that run on top of it. Node.js is also renowned for being a runtime environment. This way, it enables developers to test a software program while it's running. Moreover, it also simulates how the program will behave once it's been executed; thus, it can become possible to look for bugs or errors and fix them. Additionally, the development platform also capable of runs a programming construct called an "event loop," that handles client requests easily. This is the reason, node.js is called as a full-fledged server and more of a foundation that lets developers add libraries and workhorse connectors such as HTTP, SSL, and TCP that enable working dynamic web server quickly - all requiring only a few lines of javascript. Here are some other recognitions of Node.js: 1) You must be familiar with the MEAN software stack. But did you know, it is N in the full-stack? Mean Stack is a bundle of all the necessary components essential to building sites that are proven to work well together. MEAN is one such software stack powered by javascript. 2) It's open-source and cross-platform. 3) Did you know node.js is an asynchronous, non-blocking, event-driven I/O system? That means if your application doesn't have to wait around for an initial operation to complete before it can respond to another event. It instead ensures
queue callbacks in the event loop as it receives them, as well as perform requisites processes before the initial transmission has finished. Node brings javascript's asynchonous method to app's back-end programming. This way, it takes calls separately from one another, on an individual basis, that further supports it to handle cascading calls often made through multiple APIs. Since many believe the javascript's asynchronous method could slow-down traditional back-end programming with language like PHP. Still, we forget that it is powered by Chrome's JavaScript virtual machine, such as V8. V8 is Google's JavaScript engine, and comprehensively supports the execution of the Node's code. So, you are confused between PHP, Node, and Python, you can hire nodejs developers for your application development project.
