The term "user experience" (UX) concerns the overall perception and interaction a user has with an application or website. It involves understanding user needs, behaviors, and expectations to create intuitive and engaging interfaces. Key elements of UX design include usability, accessibility, and visual aesthetics. By focusing on these aspects, developers and designers aim to provide a seamless experience that meets user requirements and preferences. A positive UX can lead to increased user satisfaction, higher engagement rates, and ultimately, more successful products.
