What is the impact of different browser versions on web performance?

Different browser versions can significantly affect web performance due to variations in rendering engines, support for modern web standards, and optimizations. For example, newer versions often have better JavaScript engines and improved CSS handling.

Can you give me examples of specific features that might not work in older versions?

Sure! Features like CSS Grid, Flexbox, and certain JavaScript ES6+ functionalities may not be fully supported in older browsers, leading to layout issues or broken functionality.

How can I check which browser version my users are using?

You can use analytics tools like Google Analytics to track browser versions. Additionally, you can implement JavaScript to detect the user's browser and version directly.

What should I do if I find many users on outdated browsers?

If you find many users on outdated browsers, consider implementing graceful degradation or progressive enhancement strategies. You might also want to encourage users to update their browsers for a better experience.
