How long should transitions be in a React UI?
Short, around 150 to 250ms. Keep them for feedback, not decoration. Long transitions slow the UI and frustrate users, while no transitions feel instant and abrupt.

Consistent spacing and typography, hover and focus states on every interactive element, smooth short transitions, skeletons for loading, helpful empty and error states, accessible interactions, and performance work. These are what separate a finished UI from a prototype.
They give feedback that an element is interactive. Hover is for mouse users; focus is for keyboard users. Both are essential for polish and accessibility, since they show the user what they are about to interact with.
Skeletons that match the final layout, so the user sees the structure while data loads. A bare spinner works, but a skeleton gives a smoother impression of the final content and feels more polished.
