Do you have a favorite type of task on the frontend? Or conversely, what type of task do you dislike?

I enjoy tasks related to performance optimization and UX improvement — for example, implementing lazy loading, optimizing component rendering. This makes the interface faster and more user-friendly. I less enjoy doing routine layout work for complex designs with many small adjustments, especially if the design is unclear or constantly changing — it often takes a lot of time and doesn't provide creative satisfaction.
