HTML forms are important for capturing user input, while events are important for responding to user interactions. Together, they enable dynamic web pages and powerful user experiences.
Why are forms so important in web development?
Forms are important in web development because they allow users to easily provide input and data to a website for processing. Forms provide a convenient way for users to interact with web applications, allowing for data to be collected and stored.
When designing a form, what are some key things to keep in mind when it comes to user experience?
Keep the design simple, and make sure the form is easy to navigate. Make sure it is accessible and mobile-friendly, and provide clear instructions and feedback.

How would you describe events to a non-technical friend?
Javascript events are like triggers that activate a specific action on a web page when a user interacts with it, like clicking a button or hovering over a picture.
When using the addEventListener() method, what 2 arguments will you need to provide?
The first argument is the type of event, such as “click” or “mouseover”. The second argument is the function that will be executed when the event is triggered.
Describe the event object. Why is the target within the event object useful?
The event object is an object that is created by the browser when an event occurs. It contains information about the event, such as the type of event that occurred, the target element that triggered the event, and the coordinates of the mouse cursor when the event occurred. The target element is useful because it allows for the specific element that triggered the event to be identified.
What is the difference between event bubbling and event capturing?
Event bubbling is where an event is propagated up the DOM tree, while event capturing is where an event is propagated down the DOM tree.
