👉 Mockups are digital illustrations that are created to illustrate and test different versions of a product or concept. They are typically used in design, marketing, and UX/UI development as they can help stakeholders quickly see how their ideas would look when implemented on real-world devices. Mockups can be created using various software tools such as Adobe XD, Sketch, or Figma, which allow designers to visualize the different versions of a product before it is released.
