Free Response and MCQ

  1. What does CRUD stand for?
    • Create
    • Read
    • Update
    • Delete
  2. What are the HTTP verbs that are associated with each CRUD action?

  3. What is JQuery? jQuery is a fast and concise JavaScript library designed to simplify HTML document manipulation, event handling, and animation. It provides a versatile and easy-to-use framework for front-end web development, allowing developers to write less code while achieving complex functionality. jQuery simplifies tasks like DOM traversal and manipulation, making it widely used for creating interactive and dynamic web pages.

  4. Match A, B, and C into the JQuery event handler for a data table
    • A: ‘click’
    • B: ‘.delete-btn’
    • C: ‘#data-table’

    $(C).on(A, B, function() { // code });

  5. Why do we use JQUERY with CRUD? jQuery is often used with CRUD (Create, Read, Update, Delete) operations in web development for its simplified syntax and powerful features. It streamlines DOM manipulation, making it easier to handle user interactions and update content dynamically. jQuery’s concise methods reduce the amount of code needed for common tasks, enhancing the efficiency of CRUD operations. This results in a more intuitive and readable codebase, improving the developer’s productivity when implementing CRUD functionality in web applications.
