Node js is an open-source and cross-platform used for executing JavaScript code outside of the browser. Node js allows developers to build networking tools and web servers through JavaScript and module collections that handle a variety of core functionalities. This programming language is initiated to extend the use of JavaScript in the web browser. Node js offers an event-driven non-blocking I/O model, making it an outstanding tool for building scalable and robust applications. Are you getting ready to grab a job as a Node JS developer? You can easily get access to the Node JS interview questions and thus you get rid of all confusions.
JavaScript and Node js
If you are interested in developing different types of applications for your web browsers, then you must study Node js. JavaScript authorizes Node js for managing the event loop mechanism that is a Node js perk. JavaScript helps developers to run flawlessly in different OS environment.What is JSON?
JSON stands for JavaScript Object Notation and it is a get-at-able data exchange format. It is quite easy to build APIs quickly with JSON. You need to consider JavaScript while using JSON. JSON provides you with a strong and accessible data exchange format. It is a JavaScript mainstay, allowing developers to create APIs fast. Previously, programmers had to pay additional care to manipulate dynamic data in JavaScript. Thanks to JSON for giving birth to the NoSQL database, designed only for JS.Google Chrome powers Node js
The V8 engine of Google powers Node js that works on the backend, taking a similar runtime in Google Chrome for executing the JavaScript front-end. However, Node js is considered the rapid along with the most dynamic runtimes in comparison with advanced JavaScript. Moreover, Google lists it among several system engine powers. Apart from using Google developer tools, you can use Node js debugging feature to debug which enables you to eliminate errors in the front-end and back-end.Comprehensive code library
Node js provides you with a massive dependency library, called Node Package Manager. It helps developers for managing things quite easily through dependable package management, letting the Node ecosystem grow perfectly. Node Package Manager or NPM has a repository of 50,000 packages, enables developers to build useful solutions, encouraging sharing. With this inbuilt feature, it becomes simpler for you to share, update as well as reuse codes.Small yet fast working modules
The Node js framework is fragmented into several smaller modules such as Node js core and Node js application. Though you are allowed to use them together, it is not mandatory. To use both of these together at the server or client end, making it lighter.Creating real-time apps
Node js is a programming language with excellent features ideal for building real-time applications such as gaming apps and chats. Moreover, it is suitable for the programs requiring a non-blocking server or event-based server.Free sharing encourages developers
As a web developer, if you are interested in sharing your knowledge continuously then Node js can be beneficial for you. If you work on Node js, you can expect getting help quickly as well as you can easily share on the community. You can also share your different packages with different developers and help them save their time struggling with other types of packages and sources.The architecture of Node js
This programming language runs on a single thread, helps to avoid context switching. Node js performs non-blocking I/O operations through the event loop. A transaction that passes through Node traverses a callback cascade. And it uses the ‘libuv’ library to handle queuing, processing the asynchronous events.What is front-end development?
It is related to code the UI interface, managing events, and interacting with the back-end server for pulling data at the front end. The users can see the front end; it engages them to perform some activities.Betterment with time
With each passing day, Node js is getting better, continuing new releases, and in the meantime improving the standard of the features and codes. Since it is supported by an open-source community, it will be cherished in the future.Note
You must stay up to date if you are interested to establish yourself in the field of web development.
