Available answers

The x-init directive in Alpine.js is designed to run JavaScript code once when a component is initialized, making it perfect for setup code that should only execute once.
Question 2/15
😊 Your answer was correct 🙁 Your answer was incorrect
How would you declare a function that can be called within an Alpine.js component?

Available answers

Functions in Alpine.js are declared within the x-data object, making them accessible to other directives and bindings in the component.
Question 3/15
😊 Your answer was correct 🙁 Your answer was incorrect
Which Alpine.js directive is used to toggle a class without using complex JavaScript logic?

Available answers

The x-bind:class directive in Alpine.js allows toggling classes on elements dynamically based on data state.
Question 4/15
😊 Your answer was correct 🙁 Your answer was incorrect
For a button toggle operation in Alpine.js, what is the preferred method to change the button text dynamically?

Available answers

Using x-bind allows you to directly link the button's text content to data in Alpine.js, dynamically updating it based on state.
Question 5/15
😊 Your answer was correct 🙁 Your answer was incorrect
When should you use Alpine.js over a larger framework like Vue or React?

Available answers

Alpine.js is best suited for simple state management and interactivity on pages that do not require the full feature set of larger frameworks like Vue or React.
Question 6/15
😊 Your answer was correct 🙁 Your answer was incorrect
Which Alpine.js directive would you use to evaluate a JavaScript expression repeatedly at specific intervals?

Available answers

Alpine.js does not have a native directive for repeated intervals; JavaScript's setInterval can be used in combination with x-init for such functionality.
Question 7/15
😊 Your answer was correct 🙁 Your answer was incorrect
How does Alpine.js compare to larger frameworks like React or Vue in terms of setup complexity?

Available answers

Alpine.js is much simpler to set up compared to larger frameworks because it uses minimal setup and allows for quick integration into existing HTML without the need for a complex build process.
Question 8/15
😊 Your answer was correct 🙁 Your answer was incorrect
What is the main advantage of using Alpine.js in web development?

Available answers

Alpine.js is a lightweight JavaScript framework that integrates directly with HTML for making web pages interactive without the overhead of larger frameworks like React or Vue.
Question 9/15
😊 Your answer was correct 🙁 Your answer was incorrect
How do you define a loop in Alpine.js to iterate over a list?

Question 10/15
😊 Your answer was correct 🙁 Your answer was incorrect
How is client-side storage handled in Alpine.js when you need to save state?

Available answers

Question 11/15
😊 Your answer was correct 🙁 Your answer was incorrect
What is a major limitation of Alpine.js compared to frameworks like React?

Available answers

Unlike frameworks such as React, Alpine.js does not use a virtual DOM, which can limit performance optimizations for updates and renders on complex applications.
Question 12/15
😊 Your answer was correct 🙁 Your answer was incorrect
How is data reactivity handled implicitly in Alpine.js?

Available answers

Alpine.js uses JavaScript proxies to update the DOM automatically when data changes, achieving reactivity efficiently.
Question 13/15
😊 Your answer was correct 🙁 Your answer was incorrect
Which directive would you use in Alpine.js to execute JavaScript code when a component is initialized?
