Q: Which dependencies are essential for this tutorial?
A: You’ll need: spring-boot-starter-web spring-boot-starter-data-jpa MySQL connector Lombok (for boilerplate reduction)
Q: What project structure and tools does the guide recommend?
A: Use Spring Initializr to bootstrap the project, work within IntelliJ IDEA, and test endpoints using Postman.
Q: Why is Spring Boot a good fit for building REST APIs with MySQL?
A: Spring Boot simplifies setup by auto-configuring components and dependencies, letting you focus on building functionality—not plumbing.
Q: What CRUD and HTTP methods correspond in REST API design?
Create → POST Read/Retrieve → GET Update → PUT Delete → DELETE These map directly to common database operations
Q: How do I add or subtract days (or other units) to a date?
A: Retrieve the relevant value using getters (like .getDate()), adjust it numerically, and set it back via setters (e.g., .setDate()). JavaScript smartly handles overflow (e.g., adding 10 days to Sept 24 auto-advances into October).
Q: How do I customize date formatting in JavaScript?
A: Built-in methods like .toString(), .toLocaleDateString(), .toISOString(), etc., offer several formats. For fully customized output (e.g., “Sun, 24 September 2023”), manually assemble strings using methods like .getFullYear(), .getMonth(), .getDate(), combined with arrays of day or month names.
Q: What’s the safest way to create Date objects?
A: Use one of these four methods: Date string (ISO-8601 recommended) Date arguments (new Date(year, monthIndex, day, …))—note months are zero-indexed Timestamps (new Date(millisecondsSinceEpoch)) No arguments (new Date(), for the current local date/time)
Q: Why should I avoid ambiguous date strings like “14-03-2012” in JavaScript?
A: Because JavaScript may interpret ambiguous formats inconsistently, leading to “Invalid Date”. Instead, always use the ISO 8601 extended format (e.g., YYYY-MM-DD or YYYY-MM-DDTHH:mm:ssZ) for reliable parsing.
Q: Is PartyRock good only for fun apps, or can it be used professionally?
A: While PartyRock is marketed as fun and experimental, you can prototype serious use-cases like customer support bots, training tools, or idea generators before moving them to production in AWS Bedrock.
Q: What’s the role of “Dynamic Variables Chain”?
A: It lets you pass outputs from one widget into another. Example: user writes a product idea → text widget generates a business plan → another widget generates a logo. This chaining creates powerful, multi-step AI apps.
