1 - Explain Node.js event loop: It's a single threaded loop that handles incoming events (e.g., network requests) in a non blocking way, allowing for efficient handling of concurrent tasks.
2) Describe the difference between synchronous and asynchronous operations: Synchronous operations block the event loop until completion, while asynchronous operations allow the event loop to continue execution while waiting for results.
3) Explain the ExpressJS framework: A widely used framework for building web applications in Node.js, providing features like request routing, middleware, and view rendering.
4) What is MongoDB? A popular NoSQL database that uses a document oriented data model and is well suited for Node.js development.
5) Describe the benefits of using Node.js for microservices: Node.js is ideal for microservices due to its lightweight nature, non blocking architecture, and ability to handle high concurrency.
6) Explain the concept of serverless computing in Node.js: Serverless computing allows developers to build and run applications without managing servers, via platforms like AWS Lambda.
7) What is the purpose of the package.json file? It contains metadata about the Node.js project, including package dependencies, scripts, and configuration settings.
8) Describe the Node.js module system: Node.js uses a CommonJS module system, allowing code to be organized into separate modules that can be imported and reused.
9) Explain the use of npm in Node.js: npm is the Node Package Manager, a repository for publishing and consuming Node.js modules, making it easy to install and manage dependencies.
10) What are the advantages of using Node.js for real time applications? Node.js's event driven architecture and WebSocket support make it suitable for building real time applications, enabling efficient handling of high volume data streams.
11 - Describe the role of middleware in Node.js applications: Middleware are functions that intercept HTTP requests before they reach their intended route, allowing for preprocessing, validation, authentication, and other operations.
12) Explain the concept of data streaming in Node.js: Data streaming involves processing data incrementally as it becomes available, rather than waiting for the entire dataset to be retrieved.
13) Describe the difference between HTTP GET and POST requests: GET requests retrieve data from a server, while POST requests send data to a server for processing or storage.
14) What is the purpose of the Node.js REPL? The Read Eval Print Loop (REPL) is an interactive console environment that allows developers to experiment with Node.js code on the fly.
15) Describe the use of debugging tools in Node.js: Tools like Node Inspector and Chrome DevTools can help developers debug Node.js applications and identify errors, performance bottlenecks, and other issues.
