•Some key features of Node js that I’ve used within my projects include but not limited to

•Asynchronous and Event-Driven communication - Node.js operates on a non-blocking, event-driven architecture. This means that it handles multiple requests simultaneously without waiting for one task to finish before starting another. This makes it highly efficient and scalable.

NPM (Node Package Manager) - Node.js comes with “npm”, a package manager that provides access to a massive ecosystem of open-source libraries and modules, making it easy to extend the functionality of any application.

•Cross-Platform features- Node.js is cross-platform, meaning you can run it on Windows, Linux, and macOS. This flexibility makes it widely applicable for different environments.

•Led the development of modular, reusable, and maintainable frontend components, promoting separation of concerns and team autonomy.

•Developed and maintained end-to-end automated test cases using Cypress to ensure the functionality and performance of web applications.

•I/O-bound Tasks - Since Node.js is optimized for handling multiple I/O-bound operations (like reading files, querying databases, or making HTTP requests), it’s ideal for applications that require frequent interactions with a database or file system.

•Server-Side JavaScript - Node.js allows developers to use JavaScript for both client-side and server-side development, leading to more uniformity in codebases and better team collaboration between frontend and backend developers.
