Wireframes and prototypes are important tools that I use in my design process to communicate and test ideas. Wireframes are low-fidelity representations of a product's layout and content and are used to define the structure and hierarchy of a design. I might create wireframes using tools such as Balsamiq or Sketch, or even just with pen and paper. Prototypes are more interactive and high-fidelity representations of a design and are used to test and validate ideas before moving into the development phase. I might create prototypes using tools such as InVision or Figma, or even with code using tools such as HTML, CSS, and JavaScript. I use wireframes and prototypes to communicate my ideas to stakeholders, gather feedback, and identify areas for improvement.
