Using "defer" and "async" attributes in CSS and JavaScript files can enhance web performance. "Defer" ensures scripts load in order after parsing, minimizing render-blocking. "Async" loads files asynchronously, allowing them to download without blocking HTML parsing. Prioritize "defer" for scripts that rely on DOM elements, maintaining execution order. Employ "async" for independent scripts, promoting parallel downloads. Strategically apply these attributes to optimize loading and execution, ultimately improving website responsiveness and user experience.

To improve web performance, consider deferring or asynchronising CSS and JavaScript files, which means letting the browser load them without blocking the page from displaying. Defer loads scripts after the HTML is parsed, while async loads them as soon as they’re available. Prioritise loading important page elements first for a quicker display, and carefully place scripts in your HTML to control when they’re executed. Additionally, keep up with modern development techniques like using ES6 imports and CSS methodologies for better organisation and efficiency in your codebase, making your website faster and easier to maintain.

Defer and async are crucial for optimizing loading performance, especially for content-rich websites. By using defer, scripts are executed in order, ensuring dependencies are managed correctly, which is vital for scripts that rely on each other. Async, on the other hand, is best for independent scripts as it can reduce perceived load time by running scripts concurrently with page rendering. It's important to note that neither attribute works with inline script elements, and their benefits are most noticeable on scripts that are not critical to initial page rendering.

This is like scheduling tasks so you don't do everything at once and get overwhelmed. By deferring or using async, you're telling the browser it can wait to load certain files or load them in the background while it does other things. This way, the most important parts of your site load first and quickly.

Defer or async attributes allow CSS and JavaScript files to be loaded asynchronously, meaning they won't block the rendering of the webpage. This enables the browser to continue parsing and rendering HTML content while downloading CSS and JavaScript files in the background, resulting in faster page load times.
