Question 1

How to cache jQuery selectors for better performance?

Accepted Answer

Store selectors in variables to avoid repeated DOM queries. For example, use `var blocks = $('#blocks').find('li');` and reuse `blocks` in your code, as shown in the README. This reduces overhead and speeds up animations or event handlers.

Question 2

What's the best way to handle events with jQuery?

Accepted Answer

Use the `.on()` method for event binding, as recommended in the README. It supports dynamic elements, multiple events, and namespaces, making it more flexible and maintainable than older methods like `.click()`.

Question 3

jQuery vs vanilla JavaScript for DOM manipulation?

Accepted Answer

Vanilla JavaScript is often faster and more modern, but jQuery simplifies cross-browser compatibility and syntax. For new projects, consider native APIs, but jQuery remains useful for legacy code or quick prototyping.

Question 4

How to preload images using jQuery?

Accepted Answer

Create a function that loads images into memory before they're needed. The README provides `$.preloadImages = function() { ... }` to preload images on hover or other interactions, improving user experience.

Question 5

Is jQuery still relevant in modern web development?

Accepted Answer

jQuery is declining in popularity with frameworks like React and Vue, but it's still used in legacy systems. For new projects, focus on modern tools, but these tips can help maintain existing jQuery codebases.

Question 6

How to make an accordion with jQuery?

Accepted Answer

Use the simple accordion snippet from the README: bind click events to headers to toggle content with `slideToggle()`. This method hides other panels automatically, creating a basic accordion without external plugins.
