Key features of Node.js include:
Non-Blocking I/O: Node.js is designed to handle asynchronous operations efficiently, making it well-suited for applications that involve many concurrent connections.
Event-Driven Architecture: Node.js operates on an event-driven, single-threaded model. It uses an event loop to manage asynchronous operations, allowing developers to write code that is more scalable and responsive.
npm (Node Package Manager):
Key features of npm include:
Package Management: npm makes it easy to install and manage third-party libraries and packages. You can simply use the
npm install command followed by the package name to add a package to your project.
Version Control: npm allows developers to specify the version of a package they want to use. This ensures consistency in projects and helps prevent unexpected updates from breaking code.
Dependency Management: npm automatically manages dependencies for your project. When you install a package, npm will also install any other packages that the package depends on.
Scripts: npm lets you define custom scripts in your
package.json file. These scripts can be used to automate various tasks, such as running tests, building the project, or starting a development server.
Global and Local Installation: npm supports both global and local installations of packages. Global packages are typically used for command-line tools that you want to access from anywhere in your system, while local packages are specific to a project.
