What is Node.js and why use it?

Node.js is a JavaScript runtime environment that executes JavaScript code on your computer. Unlike a web browser, which can only run JavaScript code on a web page, Node.js can run JavaScript code on any file or program on your computer. This means that you can use JavaScript to perform tasks that are normally done by other programming languages, such as accessing files, databases, networks, and operating systems.

Node.js has many benefits that make it a great choice for developers, such as:

- It is fast, scalable, and efficient.

Node.js uses an event-driven and non-blocking architecture, which means that it can handle multiple requests and tasks without waiting for one to finish before moving on to the next. This makes Node.js very fast and responsive, especially for applications that involve a lot of input/output (I/O) operations, such as web servers, chat applications, and streaming services. Node.js can also scale up or down easily by adding or removing processes or machines, depending on the demand.

- It has a large and active community of developers and modules.

Node.js is one of the most widely used and supported JavaScript runtime environments in the world. It has a huge and active community of developers who contribute to its development and improvement. It also has a rich ecosystem of modules (also known as packages or libraries) that provide various functionalities and features for Node.js applications. You can find and install thousands of modules from the npm registry, which is the official package manager for Node.js. You can also create your own modules and share them with other developers.

- It can be used for various purposes, such as web development, data analysis, scripting, and automation.

Node.js is very versatile and flexible, which means that you can use it for different types of applications and projects. For example, you can use Node.js for web development, where you can create dynamic and interactive web pages using HTML, CSS, and JavaScript. You can also use Node.js for data analysis, where you can process and manipulate large amounts of data using JavaScript libraries like D3.js or TensorFlow.js. You can also use Node.js for scripting and automation, where you can write scripts that perform various tasks on your computer or other devices using JavaScript commands.

What is Node.js 12 and what are its features?

Node.js 12 is the latest Long Term Support (LTS) version of Node.js, which means that it will receive security updates and bug fixes until April 2022. LTS versions are recommended for production environments because they are more stable and reliable than non-LTS versions. Node.js 12 was released in October 2019 and has some new and improved features that make it more performant and secure than previous versions. Some of these features are:

- Improved performance and stability.

Node.js 12 has improved its performance and stability by updating its core components and dependencies. For example, it has updated its V8 engine (the JavaScript engine that powers Node.js) to version 7.8, which brings faster execution speed and lower memory usage. It has also updated its libuv library (the library that provides cross-platform I/O operations) to version 1.31, which brings better support for threads and file system events.

- Support for ES2019 syntax and features.

Node.js 12 supports the latest ECMAScript standard (ES2019), which is the official name for JavaScript. This means that you can use new syntax and features that make your code more concise and expressive. For example, you can use optional catch binding (which allows you to omit the error parameter in a catch block), object.fromEntries (which converts an array of key-value pairs into an object), flat and flatMap methods (which flatten nested arrays into one-dimensional arrays), string.trimStart() and string.trimEnd() methods (which remove whitespace from the beginning or end of a string), etc.

- Enhanced security and cryptography.

Node.js 12 has enhanced its security and cryptography by adding new features and options that make your applications more secure. For example, it has Node.js 12 has enhanced its security and cryptography by adding new features and options that make your applications more secure. For example, it has added support for TLS 1.3 (the latest version of the Transport Layer Security protocol that encrypts and authenticates data over the internet), which brings faster and more secure connections. It has also added support for OpenSSL 1.1.1 (the latest version of the open source software library that provides cryptographic functions), which brings support for new algorithms and ciphers, such as ChaCha20-Poly1305 and AES-256-GCM. It has also added a new experimental feature called policy, which allows you to restrict the modules that can be loaded or executed by your application.

- Experimental support for modules and workers.

Node.js 12 has added experimental support for two new features that are still under development and may change in the future: modules and workers. Modules are a new way of organizing and importing JavaScript code that follows the ECMAScript Modules (ESM) specification. Modules allow you to use the import and export keywords to load and export code from different files, instead of using the require and module.exports keywords that are used by the CommonJS module system. Workers are a new way of creating and managing multiple threads of execution that can run JavaScript code in parallel. Workers allow you to use the Worker class to create new threads that can communicate with the main thread using message passing, instead of using the child_process module that spawns new processes.

How to download and install Node.js 12 on your computer?

Depending on your operating system, there are different ways to download and install Node.js 12 on your computer. Here are some common methods:

- Windows: You can use the Windows Installer or the Windows Binary from the official Node.js website. Alternatively, you can use a package manager like Chocolatey or Scoop.

The Windows Installer is an executable file that will guide you through the installation process and set up Node.js and npm on your computer. The Windows Binary is a zip file that contains the Nod
