UI
User interface — the visual and interactive surface a human uses to operate software.
Definition
User Interface is the layer of software a human directly perceives and operates: visual layouts, controls, text, animations. UI is one half of UX (user experience), the other being the underlying flow and meaning of those interactions. Modern web UIs are built with React, Vue, Svelte, or HTML+CSS; native desktop UIs use platform toolkits.
