Question 1

How to dynamically load multiple JavaScript files in order with LazyLoad?

Accepted Answer

Pass an array of URLs to the js() method; LazyLoad automatically handles order by loading sequentially in browsers that don't support parallel execution, as per the caveats. For example, LazyLoad.js(['file1.js', 'file2.js'], callback).

Question 2

LazyLoad vs RequireJS: which should I use for lazy loading?

Accepted Answer

LazyLoad is a minimal tool focused solely on loading JS/CSS files, ideal for simplicity and small size. RequireJS offers full dependency management but is larger. Choose LazyLoad if you only need basic on-demand loading without complex dependencies.

Question 3

Is LazyLoad compatible with modern frameworks like React or Vue?

Accepted Answer

It can be used in any JavaScript environment, but modern frameworks often have built-in lazy loading (e.g., React.lazy). LazyLoad works at a lower level, so integration might require extra effort and isn't optimized for component-based architectures.

Question 4

Does LazyLoad support loading images or other assets?

Accepted Answer

No, it's specifically designed for JavaScript and CSS files only, as stated in the description. For images, you'd need a different solution, such as the native loading='lazy' attribute or a dedicated image lazy loader.

Question 5

How to handle errors if a file fails to load with LazyLoad?

Accepted Answer

LazyLoad doesn't provide built-in error handling; callbacks only fire on success. You'd need to implement workarounds, like setting timeouts or checking for global variables, which adds complexity compared to more feature-rich loaders.

Question 6

What are the best alternatives to LazyLoad for current projects?

Accepted Answer

Modern alternatives include using native import() for JavaScript, dynamic link elements for CSS, or actively maintained libraries like loadjs or yepnope. These offer better features, maintenance, and compatibility with contemporary web standards.
