What are the best practices for using polyfills in web development?
When using polyfills, it's important to only include those that are necessary for your target browsers. This helps keep your code lightweight.
How do I determine which polyfills I need?
You can use tools like Can I Use to check browser compatibility for specific features and then decide which polyfills to implement.
Are there any performance considerations I should be aware of?
Yes, loading too many polyfills can slow down your site. It's best to load them conditionally based on the user's browser.
Can you give me an example of a commonly used polyfill?
A commonly used polyfill is the 'fetch' polyfill, which allows you to use the Fetch API in browsers that do not support it.
