What is Node.js Technology?

Many technical companies like eBay, Yahoo, and Microsoft are using the most recent technology that is Node.js. If you wish to go in developing field then Node.js is the perfect option to get higher opportunities. Applications build in Node.js are exceedingly scalable or you can categorize them as a real time apps. Many programmers still refuses to use JavaScript at back-end and this is the reason why they not want to work using Node.js. Many developers do not know how to use it or when to use that’s why still Node.js is unpopular among many developers in technical companies.

Things to know about Node.js are:

V8 is the engine on which the Node executes Java Script that was developed by Google so that it can be used in their one and only web browser, Chrome. If we leverage V8 then it allows the Node to run Java Script at the faster speed by offering server-side run time environment. This speed gets faster because of the fact that Java Script is compiled by V8 into native machine code rather executing or interpreting it as the bytecode. Node is an open source technology that has the cross platform. It may run on three platforms Linux, Windows and Mac OSX.

You must be thinking- Why Java Script on the server side? As Java Script has already transferred to the tedious work in the web browser, because it is a complete functional programming language that is capable to do anything just more than the traditional languages like: C++, Java, Ruby and so on. The language that is perfect for the asynchronous programming is Java Script. All the pros that the best event model has are well equipped in Java Script language. Many thousands of web developers are know about this language very well. They are well versed with this language in developing many website.

Node.js Real Time Applications

As we talk about the Node.js real time applications, in this the updates request is send by the client browser constantly to the server. This process is also known as polling. If the web server has an update then the response is send by it to the client browser and then the new information is made available to the client browser. In the real time applications as the request frequency increases, the resources that are needed to handle them also increases.

As per the Node the operating system should be informed about the creation of the new connection and after that it go to ideal mode that is sleep mode. In case any new connection then the callback is executed by it.
