Question

Accepted Answer

Answers to various technical questions related to Node.js, Java, Docker, and Spring Boot.

Node.js uses event-driven, non-blocking I/O model for asynchronous programming, while Java uses threads for concurrency.
In Node.js, asynchronous operations are handled using callbacks or promises, whereas Java uses CompletableFuture or RxJava for asynchronous programming.
docker add copies files from the source directory and adds them to the image, while docker copy copies files from the host machine to the container.
Accept is an HTTP header that specifies the media types that the client can understand, while Content-Type specifies the media type of the request being sent.
Rate limiting can be implemented using algorithms like Token Bucket or Fixed Window.
Prototype scope in Spring Boot creates a new instance of a bean each time it is requested, while Singleton scope creates a single instance of a bean for the entire application context.
