Node.js is a JavaScript runtime environment that uses Google Chrome's V8 engine. It allows for high concurrency without threads or processes by using an event loop and callbacks for non-blocking I/O. While it can be used for server-side JavaScript applications, its lack of access to the DOM from the server-side presents some drawbacks compared to traditional client-side JavaScript. Overall, Node.js enables highly scalable applications but its non-blocking nature requires some adjustment for developers accustomed to blocking I/O models.Node js crash course session 2

JavaScript code may be run outside of a web browser Thanks to the open-source, cross-platform runtime environment known as Node.js. Ryan Dahl first presented it in 2009, and it has subsequently gained popularity as a server-side programming language.
In this post, we'll examine Node. Js' fundamentals and how server-side programming might benefit from it. We'll also look at some of Node. Js' essential attributes have helped it become so well-liked by programmers.
Overview of Node.js
A server-side runtime environment called Node.js was constructed on top of Google's V8 JavaScript engine. Developers can now employ JavaScript, which was previously solely used on the client side, to create server-side code. With the help of Node.js, programmers can build highly scalable, event-driven apps that can manage several concurrent connections.
History of Node.js
Developer Ryan Dahl first released Node.js in 2009 with the goal of enabling JavaScript programmers to build highly scalable network applications. He developed Node.js on top of the Google Chrome-compatible V8 JavaScript engine and made it available as an open-source project.
Benefits of Node.js
The use of Node.js for server-side development has a number of advantages. A few of these are:
Performance: The V8 JavaScript engine, which is highly optimized for performance, is the foundation upon which Node.js is constructed. Because of this, Node.js apps can handle numerous connections at once without experiencing performance issues.
Scalability: Node.js applications have a great degree of scalability and can manage numerous concurrent connections without the installation of additional hardware.
Easy to Learn:Node.js is reasonably simple to learn because it leverages JavaScript, a well-known language among developers.
Large Community: Node.js has a sizable developer community that supports one another and contributes to the open-source project.
Introduction to Node.js
Setting up Node.js
You must install Node.js on your computer before you can begin using it. Node.js can be downloaded from the official Node.js website, which also provides installation guidance.
figuring out npm
Developers may quickly install and manage dependencies for their Node.js apps using npm (Node Package Manager), a Node.js package manager. There is no need to install npm individually because it is part of Node.js.
Basics of Node.js
Knowledge of the Event Loop
On top of an event-driven, non-blocking I/O mechanism, Node.js is constructed. This indicates that Node.js processes numerous jobs concurrently by using an event loop rather than waiting for I/O operations to finish before going on to the next task. Because of this, Node.js apps can handle numerous connections at once without experiencing performance issues.

Node.js is an open-source JavaScript runtime environment for developing server-side web applications. It allows JavaScript to be used on the server-side for networking and server-side scripting. Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, suitable for data-intensive real-time applications that run across distributed devices. Some key features include using JavaScript for server-side development, being event-driven and non-blocking to handle multiple concurrent connections without blocking the event loop, and using Google's V8 JavaScript engine for speed and performance.Node Js Non-blocking or asynchronous Blocking or synchronous.pdf

Node.js is a server-side scripting language based on Googles V8 Javascript engine. Node js is a single-threaded and highly scalable system. Instead of separate processes and threads, it uses asynchronous, event-driven I/O operations. So It can achieve high output via single-threaded event loop and non-blocking I/O.

Node.js: Why and Where to Use It?
Node.js has gained immense popularity in recent years due to its unique features and capabilities. It is a powerful JavaScript runtime built on Chromes V8 JavaScript engine, which enables developers to build scalable and high-performance applications. In this article, we will explore the reasons why you should consider using Node.js and where it can be most beneficial.
Why to Use Node.js?
Efficient and Scalable:
Node.js is known for its efficiency and scalability, making it an excellent choice for developing applications that can handle a large number of concurrent connections. It uses an event-driven, non-blocking I/O model, allowing it to handle multiple requests without getting blocked, unlike traditional blocking I/O models used in other languages. This makes Node.js ideal for applications that require real-time interactions, such as chat applications, collaborative tools, and gaming platforms.
Single Language, Full Stack:
One significant advantage of Node.js is that it enables developers to use JavaScript both on the server and the client side. This means that you can have a seamless development experience, using the same language and libraries throughout the entire stack. This consistency reduces the complexity of development and eases the transition between front-end and back-end development tasks. It also enables the reuse of code and modules, resulting in faster development cycles and increased productivity.
Large and Active Community:
Node.js has a vibrant and extensive community of developers, which means you can easily find support, libraries, and resources to help you in your Node.js development journey. The community actively contributes to the Node Package Manager (NPM), which hosts a vast collection of open-source packages that can be easily integrated into your projects. With a rich ecosystem and continuous community-driven enhancements, Node.js ensures that you can find solutions to most of your development challenges.

Node js first look - 2016
- 2. package ecosystem, npm, is the largest ecosystem of open source libraries in the world. is a JavaScript runtime built on Chrome's V8 JavaScript engine. uses an event-driven, non-blocking I/O model that makes it lightweight and ef鍖cient. allows the creation of Web servers and networking tools using JavaScript
- 3. is the JavaScript execution engine built for Google Chrome and open-sourced by Google in 2008. Written in C++, V8 compiles JavaScript source code to native machine code instead of interpreting it in real time.
- 4. is a package manager for the JavaScript programming language. It is the default package manager for the JavaScript runtime environment NodeJS It consists of a command line client, also called npm, and an online database of public packages, called the npm registry The registry is accessed via the client, and the available packages can be browsed and searched via the npm website
- 5. All APIs of NodeJS library are asynchronous, that is, non- blocking. It essentially means a NodeJS based server never waits for an API to return data. The server moves to the next API after calling it and a noti鍖cation mechanism of Events of NodeJS helps the server to get a response from the previous API call.
- 6. NodeJS allows to create a scalable and fast web server in simple way by using JavaScript. Opportunity to write client-side and server-side parts of web application on your favourite JavaScript sounds appealing!
- 7. We will need: Knowledge of the basics JavaScript language Installed NodeJS (https://nodejs.org) Any text redactor / IDE Terminal LET'S MAKE A SIMPLE SERVER WITH NODEJS (1/5)
- 8. Preparation: Create project folder Add server.js to project folder Install node-router package via npm LET'S MAKE A SIMPLE SERVER WITH NODEJS (2/5)
- 9. Add some code { LET'S MAKE A SIMPLE SERVER WITH NODEJS (2/5)
- 10. Run our server.js LET'S MAKE A SIMPLE SERVER WITH NODEJS (3/5)
- 11. LET'S MAKE A SIMPLE SERVER WITH NODEJS (4/5) And check the result in browser
- 12. As we can see at network tab, when we call origin. Browser automatically send GET request to ORIGIN. According the code if someone sent a request for origin then NodeJS send back a response with text "Hello!" Looks 鍖ne and easy, isn't it?
