What is cache busting and why is it important?

Cache busting is a technique used to force browsers to load the latest version of a resource, like CSS or JavaScript files. It's important because browsers often cache these resources to improve load times, but this can lead to users seeing outdated content.

How can I implement cache busting in my web project?

You can implement cache busting by appending a version number or a unique query string to your resource URLs. For example, instead of linking to 'style.css', you could link to 'style.css?v=1.0'.

Are there any tools that can help with cache busting?

Yes, many build tools like Webpack and Gulp can automate cache busting by appending hashes to filenames whenever the content changes.

What are the downsides of cache busting?

The main downside is that it can lead to increased load times if not managed properly, as users may have to download new files more frequently.
