NodeJs
Node.js is an open-source, cross-platform, back-end JavaScript runtime environment that runs on the V8 engine and executes JavaScript code outside a web browser.
What is NodeJS?
Node.js is an open-source and cross-platform JavaScript runtime environment. It is a popular tool for almost any kind of project!
Node.js runs the V8 JavaScript engine, the core of Google Chrome, outside of the browser. This allows Node.js to be very performant.
How does NodeJS work?
A Node.js app runs in a single process, without creating a new thread for every request. Node.js provides a set of asynchronous I/O primitives in its standard library that prevent JavaScript code from blocking and generally, libraries in Node.js are written using non-blocking paradigms, making blocking behavior the exception rather than the norm.
When Node.js performs an I/O operation, like reading from the network, accessing a database or the filesystem, instead of blocking the thread and wasting CPU cycles waiting, Node.js will resume the operations when the response comes back.
This allows Node.js to handle thousands of concurrent connections with a single server without introducing the burden of managing thread concurrency, which could be a significant source of bugs.
Node.js has a unique advantage because millions of frontend developers that write JavaScript for the browser are now able to write the server-side code in addition to the client-side code without the need to learn a completely different language.
A Vast Number of Libraries
npm with its simple structure helped the ecosystem of Node.js proliferate, and now the npm registry hosts over 1,000,000 open source packages you can freely use.
Frequently Asked Questions
Node allows developers to write JavaScript code that runs directly in a computer process itself instead of in a browser. Node can, therefore, be used to write server-side applications with access to the operating system, file system, and everything else required to build fully-functional applications.
It’s lightweight, efficient, and its ability to use JavaScript on both frontend and backend opens new ways for development. That’s why it is not surprising that lots of major and popular industry leaders chose to rely on Node. js. Each of those companies has a unique and interesting story about Node.
Here are the companies using Node. js: Netflix, NASA, Trello, PayPal, LinkedIn, Walmart, Uber, Twitter, Yahoo, eBay, GoDaddy, and got much better results. Quick Summary :- You might have heard how Node. js apps power businesses with high speed & performance.
Node is better for web applications and website development whereas Python is best suitable for back-end applications, numerical computations and machine learning. Nodejs utilize JavaScript interpreter whereas Python uses CPython as an interpreter.
