  1. I didn’t like this article. It is very vague and does not explain how will-change works. It does not even mention that the mdn documentation advise to avoid using it if not necessary.

    Warning: will-change is intended to be used as a last resort, in order to try to deal with existing performance problems. It should not be used to anticipate performance problems.

    Repeating that it will make animations run more smoothly or improve performance does not explain how it works on when it should be used.

    In my opinion it is better to just read the mdn documentation page as it reads better and has more information. A novice after reading this article may think that it is fine to apply will-change on any element that will change.

    1. Thank you for your feedback. I’m sorry if the article wasn’t as clear as you would have liked. I did mention in the introduction and conclusion that will-change should be used with caution as it can do more harm than good if used incorrectly. I agree that the MDN documentation is a valuable resource, and I encourage anyone who wants to learn more about will-change to read it. Thank you again for your comment.

    1. Thanks for your comment. I’m glad to see we both agree that will-change should only be used as a last resort, which I mentioned in the introduction and conclusion of my article. It’s important to use this CSS property with caution and only when necessary. If you have any other feedback, I’d be happy to hear it. Thanks again.
