Scenario

Used in web pages to dynamically update content. For instance, a news website can load new articles on the homepage without reloading the entire page, enhancing user engagement.

Example

button.addEventListener('click', () => alert('Button clicked!'));

Scenario

Essential for interactive UI elements. For example, a form validation system can respond instantly to user input, providing live feedback on incorrect or missing data before the form is submitted.

Example

fetch('/api/data').then(response => response.json()).then(data => console.log(data));

Scenario

Used to retrieve data from a server without refreshing the page. E-commerce sites often use this for real-time inventory updates, or social media platforms for loading new posts as users scroll.

Example

let total = prices.reduce((sum, price) => sum + price, 0);

Scenario

Useful for calculations and processing data on the client side. For instance, an online calculator or a financial dashboard can compute totals or trends instantly, improving responsiveness.

Example

localStorage.setItem('theme', 'dark');

Scenario

Enables storing user preferences locally. A website can remember a user's theme preference or shopping cart contents, providing a personalized experience even when the user returns after days or weeks.
