UX Design, or User Experience Design, is the process of designing and optimizing a digital product to provide users with a seamless, efficient, and enjoyable experience. UX Design involves researching user needs and behaviors, creating user personas and journey maps, and testing various design elements to ensure that the product meets user expectations and requirements. UX Design encompasses not only the visual aspect of the product but also its functionality, usability, and overall interaction, aiming to create a positive and satisfying user experience.
