Full-Stack Web Dev Final Exam

MERN Stack components and purposes? M only

MongoDB - NoSQL database (stores data)

MERN Stack components and purposes? E only

Express - Node.js framework (handles routing)

MERN Stack components and purposes? R only

React - Front-end library (builds UI)

MERN Stack components and purposes? N only

Node.js - JavaScript runtime (runs JS on server)

JavaScript vs Java?

JS = interpreted, dynamic, web-focused. Java = compiled, static, enterprise. Different languages despite similar names.

MongoDB/NoSQL advantages?

Flexible schema, horizontal scaling, faster for unstructured data, JSON-like storage, easier for changing requirements.

Node.js?

JavaScript runtime for server-side. Event-driven, non-blocking I/O.

npm?

Node Package Manager - installs and manages dependencies.

nodemon?

Auto-restarts server when files change during development.

package.json?

Config file with project metadata, dependencies, and scripts.

PUG / View engines?

Template engines that generate HTML server-side with simplified syntax.

Routers?

Organize routes/endpoints by grouping related HTTP requests.

Controllers?

Functions with business logic - handle requests, interact with models, send responses.

Models?

Define data structure, validation, and database interaction methods.

Mongoose / ORMs?

ODM for MongoDB - provides schemas, validation, query building. Maps objects to database.

Promises / Async programming?

Handle async operations without blocking. Promises represent future values. Use .then()/.catch() or async/await.

React purpose?

Build interactive UIs with reusable components. Virtual DOM for efficient updates.

React vs PUG?

React = client-side, SPAs, instant updates without reload, dynamic interactivity. PUG = server-side only.

React State?

Stores component data that changes. Updates trigger re-renders for interactivity.

TypeScript purpose?

Adds static types to JavaScript. Catches errors pre-runtime, better IDE support, easier maintenance.

Agentic coding?

AI agents autonomously write, debug, refactor code with minimal human input.

Wellness goals concept?

Work-life balance, avoid burnout, regular breaks, manage stress, prioritize mental/physical health while coding.
