Overview of this book

If you're looking for a programming language to develop flexible and efficient apps, JavaScript is a great choice. However, while offering real benefits, the complexity of the entire JavaScript ecosystem can be overwhelming. This Workshop is a smarter way to learn JavaScript. It is specifically designed to cut through the noise and help build your JavaScript skills from scratch, while sparking your interest with engaging activities and clear explanations. Starting with explanations of JavaScript's fundamental programming concepts, this book will introduce the key tools, libraries and frameworks that programmers use in everyday development. You will then move on and see how to handle data, control the flow of information in an application, and create custom events. You'll explore the differences between client-side and server-side JavaScript, and expand your knowledge further by studying the different JavaScript development paradigms, including object-oriented and functional programming. By the end of this JavaScript book, you'll have the confidence and skills to tackle real-world JavaScript development problems that reflect the emerging requirements of the modern web.

Activity 4.01: Adding an Animation to the Todo List Application

Solution:

  1. Go to https://packt.live/34LCqN5 and get the jQuery CDN URL.
  2. Load the library into the head tag of your existing Todo-List-HTML using a script tag. This will allow you to use jQuery within your code:
    <head>
        // ... links and meta tags from the previous activity
    <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>
    </head>

    Inside activity.js, you need to change the todoEle variable. Change it to a jQuery element:

    // The todo list element
    // let todoEle = document.getElementById('todo-list'); // old
    let todoEle = $('#todo-list'); // new

    Inside the replaceListElements function, you can now use functions on the todoEle element that jQuery provides you with.

  3. Hide and clear what's inside the element using the necessary jQuery functions:
    function replaceListElements(listEle...
