Can you explain how polyfills affect the performance of a web application?
Polyfills can impact performance by adding extra code to support older browsers, which may slow down execution.
Are there specific scenarios where polyfills are more detrimental to performance?
Yes, if a polyfill is large or if it's used in performance-critical paths, it can significantly slow down loading times.
How can I minimize the performance impact of using polyfills?
You can minimize impact by only including necessary polyfills, using lightweight alternatives, and loading them conditionally.
What tools can help me analyze the performance impact of polyfills?
Tools like Lighthouse, WebPageTest, and browser developer tools can help you analyze and measure the impact of polyfills.
