Why Node.js is so popular:

Why Node.js is so popular

Slide2:

Why use Node.js? Node.js is used by developers because it comes with an innovative push technology to replace WebSockets.Node.js allows you to create web applications with real-time two-way connections so that the client and the server can both initiate communication, subsequently improving the exchange of important data. The main language of Node.js is JavaScript server technology. Node.js uses a wide variety of plugins which are managed via the Node Package Manager. This allows you to create custom applications tailored to your specific needs.

The main language of Node.js is JavaScript server technology. Node.js uses a wide variety of plugins which are managed via the Node Package Manager. This allows you to create custom applications tailored to your specific needs. Why use Node.js and not some other web technology? Node.js comes with a set of features that developers seem to prefer when building web applications. Here are a few: 1. JavaScript throughout: Node.js is such a popular choice among developers mainly because it uses JavaScript as its primary language. The transition from internet technologies to Node.js maybe a gentle transition while not important obstacles given the widespread nature of JavaScript as a programming language. In addition, JS remains the only way to create web applications in the browser.

Slide5:

2. Super-fast: Node.js is essentially a JS runtime environment. The development of Google to use in Chrome, V8 can compile and run JS super-fast because it compiles JS in native machine code. The Node.js event loop is a single thread that performs all I / O operations asynchronously, that is when an application needs to perform I / O operation, the application will send asynchronous tasks and a callback action to the Node.js loop event while terminating the rest of the program. Once the synchronization operation is completed, the magic event loop of Node.js returns to the task to execute a callback action. So Node.js is unique because conventional event looping takes up a lot of memory and is extremely difficult to implement.

Slide6:

3. Lightweight: Since it is based on event design, each call, and operation executed on Node.js as an asynchronous callback series, which means that Node.js can execute on a single thread without needing a new thread to be generated for each new customer request. This ability makes Node.js fast and light, creating the foundation for Nod.js' non-blocking I / O function. 4. One language in all layers: Most web technologies involve knowledge of two languages: one for the server-side and one for the client-side. With Node.js, you don't need to know two languages; you just need to know JavaScript and use it on multiple layers. In addition, the language is reusable.

Slide7:

5. High performance: Node JS high performance has been demonstrated by some of the world's giants, including PayPal, Walmart, and LinkedIn. PayPal reports having reduced response time by 35% and doubled the number of requests. The Walmart server did not exceed 1% of CPU on Black Friday in 2013 with more than 200,000,000 users online. LinkedIn reports going from 30 to 3 servers after migrating from Ruby to Node.js. 6. Host it anywhere: With the increasing popularity and widespread use of Node JS, many cloud-based web servers and hosts support Node-based applications, including Amazon AWS, Google, Microsoft IIS, Heroku, Microsoft Azure, etc.

Slide8:

7. Easy to alter and maintain: Many applications crash because they are subject to too many new requirements and cannot cope with the additional stress. But Node.js is different. Instead of creating a large application, it allows you to create multiple small applications, which makes it much easier for you to implement changes or even improve functionality simply because you don't have to go into the codebase to make these changes. 8. Real-time data streaming: There are so many reasons why to use Node.js instead of other solutions. One of those reasons is real-time data streaming, as it allows developers to create great features, including the ability to process files when they are uploaded, which is time-efficient. Real-time data streaming is a beneficial feature that programmers/developers use when working on audio encoding or real-time video encoding.

Slide9:

9. Working as a proxy server: Node.js works as a proxy server for services that have different response times. Additionally, you can stream data from a variety of sources when you choose Node.js. 10. Great community support NPM: Node.js is supported by large community that continually focuses on improving Node.js. Communities offer many code modules and packages to help developers build web applications. There is an online archive called Node Package Manager, where developers can access published Node.js projects.

Slide10:

11. Winning database queries: It is easy to combine Node.js with new NoSQL databases, including CouchDB or MongoDB, because database queries are written in JS. Node.js does not require data conversion due to the JSON stored date format. As a result, conversions from JSON to binary modules are out of the equation with Node.js, unlike Ruby on Rails. Summary: With the growing popularity of Node.js and its great possibilities, developers can create robust and highly scalable applications. Developers can now use Node.js to quickly and easily build the most extraordinary web applications, which makes Node.js a trendy JS runtime environment.
