Pagination in JPA allows for retrieving a subset of results from a query by specifying a limit and offset.

• Use the setFirstResult() method to specify the starting index of the results to retrieve

• Use the setMaxResults() method to specify the maximum number of results to retrieve

• Combine setFirstResult() and setMaxResults() to implement pagination in JPA queries

To create a RESTful API, define endpoints, use HTTP methods, handle requests and responses, and follow REST principles.

• Define endpoints for different resources (e.g. /users, /products)

• Use HTTP methods like GET, POST, PUT, DELETE for CRUD operations

• Handle requests and responses in JSON format

• Follow REST principles like statelessness, uniform interface, and client-server architecture

A closure is a function that has access to its own scope, as well as the outer scope in which it was defined.

• Example: function outerFunction() { let outerVar = 'I am outer'; return function innerFunction() { console.log(
