What is Node JS?
How To Use Node JS ?
- Temperate Literals
As asynchronous programming is a large part of Node.js, it’s also advantageous to have an understanding of:
- A-Synchronous Programming and Callbacks
- The Event Loop
Download and Install
Next, download the program for Windows or Mac from its official website found here. Included on their website are separate links for Linux and AIX. It is recommended to check out a Node Version Manager (NVM) to manage the installation of various node versions on your system. Separate NVMs are available from Github. Separate packages are available for all operating systems. NVMs give you the ability to install any version of Node.js you prefer and switch between versions.
Run The Program with ‘Hello World’
To begin, use the node command as follows:
If performed correctly, the program will output the following command:
Congratulations, now your computer works as a server!
Your coding experience and expertise will be essential here, and the learning curve can vary from coder to coder. Asynchronous programming may prove difficult to get correct with the runtime environment. In return, Node.js can handle hundreds or even thousands of data requests without interrupting data flow. While time-consuming to adjust to, the language is a great jumping-off point for full-stack development.
For Which Cases Can Node JS Be Used?
While adjusting to and learning Node.js will involve much patience, it proves useful in a number of cases thanks to its open-source functionality:
Companies such as Netflix, Youtube, and Hulu are facing stronger competition as the marketplace is flooded with new and exciting streaming services. The new generation of content providers gives users access to endless data that can be viewed anywhere from any device.
Node.js optimizes streaming by breaking up data into chunks, making it feasible to playback content bit by bit rather than downloading the entire file at once, creating a much more enjoyable user experience that does away with long buffering times.
Have you ever wondered how social media platforms such as Instagram, Spotify, or Twitter can personalize your news feeds feed? These companies know and trust Node.js to optimize client performance. User experiences can be scaled to support varying amounts of users.
American social networking company LinkedIn, for example, utilizes Node.js to handle its large amount of traffic. The organization cited much faster performance and the ability to consolidate development personnel in their support of it.
Education and Distance Learning
The unfortunate events of 2020 have resulted in an uptick in online education and distant learning services and web applications.
Node.js is an efficient and effective way to grow your e-commerce store, and is used widely by companies such as eBay and Walmart, The software’s asynchronous, event-driven architecture creates quick and efficient scalability. Frameworks from Meteor.js and Total.js offer unique features in support of e-commerce and lay the foundation for web applications and program interfacing. Other frameworks integrate inventory management, shop customization, cart & checkout, plus much more.
Why Should Your Business Consider Using Node JS?
Trello, Uber, Netflix, Yandex, Paypal, Walmart, and NASA all use node.js for their dynamic website needs.
Unbelievably quick, personalized, and interactive web experiences are why countless companies are becoming more familiar with the software. Increased internet and mobile phone usage worldwide, and the ongoing trend towards digitalization are creating fierce competition in online marketplaces.
