Node.js has gained huge success in very less time since the initial release in 2009. The list of top companies using Node.js is NASA, PayPal, Netflix, Linked In, Uber and many more is the proof of worldwide acceptance of Node.js. Common thing is that these all companies, I have mentioned above has a huge number of the user base. And Node.js is all capable to deliver the efficient performance.

What is Node.js?

  • An open-source server environment
  • Node.js is free(Managed by the community)
  • Runs on various platforms(Windows, Linux, Unix, Mac OS X, etc.)
  • Uses JavaScript on the server
  • Asynchronous programming on the server. More in detais about Node.js…

1. Full-stack development with/only Javascript


5 Facts to know about Node.js Development

You are all set to develop a complete website with JavaScript. We have had JavaScript in front-end web development but now using Node.js Anyone can use JavaScript in the back-end also and using JavaScript in the back-end is something else. We can use another programming language but JavaScript is the simplest and the most popular way to develop apps in the browser. Developers enjoy writing codes in JavaScript due to its ease of debugging and the dynamic nature of JavaScript makes it more ease. You can use other technology but it is not that much easy. Either it belongs to the small community which may lead to depreciation or the performance and the lopping is not that much effective.

Node helps us to solve the boundary between browser and server by enabling both the browser and server written in JavaScript. It is difficult to work dependently like the server-side team and the browser side team working dependency. In Node.js development need to focus only two major part first one is JavaScript and another is your Database stack like MongoDB, PostgreSQL or MySql

2. Powered by Google Chrome(The V8 JavaScript Engine)

5 Facts to know about Node.js Development

V8 is the name of the JavaScript engine that power Google Chrome. It is the things that take our JavaScript and executes it while browsing with Chrome.V8 provides the run time environment in which javascript executes. The DOM and the other web platform APIs are provided by the browser which makes it easy to run.

Others browsers have their own JavaScript engine like Firefox has Spidermonkey.
Safari has JavaScriptCore(also called Nitro).
Edge has Chakra

3. The Power of NPM, Modules and Instrument

5 Facts to know about Node.js Development

NPM stands for Node Package Manager. It included default methods in Node which provides a different kind of packages to Node. NodeJs provides a run time environment for Node. The packages make Node more specials. The reason is that a developer need not do extra work just need to include these packages and use according to need. It’s same like you are including a file in your code to use it.
Package Manager makes it easy for JavaScript developers to share the code that they have created to solve particular problems and for other developers to reuse that code in their own application.

4. Importance of JSON

JSON is not just a text format. JSON stands for JavaScript Notation format. It plays a very important role in developing APIs and Mobile Applications. In real-time development either it is an App or Website development there is always sending and retrieving of data is important. If you are not managing it in the right way. the direct effect will show the performance of the Application. JSON is a robust and popular data exchange format.

It is one of the most important pillars of JavaScript which allow Developers to build quick APIs. That provides ease to fetch data from Database and Developers can use it dynamic way.

5. Asynchronous Nature at Server

Javascript is asynchronous in nature and so is Node.js. Asynchronous programming is the design pattern which ensures non-blocking execution. It means a block of code do not prevent the execution of another block of code it in in JavaScript is asynchronous in nature and so is Node.js. Asynchronous programming is the design pattern which ensures non-blocking execution. It means a block of code do not prevent the execution of another block of code it is totally independent of each other. This improves the efficiency of the system and throughput. Asynchronous programming great for faster execution of the program but it comes with price means it’s little hard because of its callback scenario.pendent of each other. This improves the efficiency of the system and throughput. Asynchronous programing great for faster execution of the program but it comes with price means it’s a little bit hard because of its callback scenario.
