A component is a reusable element with adjustable properties such as size, state, theme, and more. Components can range from being primitive, like an Icon element, to complex, like a Header. They can be static, like a Logo, or interactive, such as a Dropdown that opens an overlay on hover or click, and/or functional, like a Link that navigates to a different route on click.

In UI development, components help maintain design consistency, resulting in a better user experience. They reduce the size of the codebase, leading to improved maintainability and scalability. Utilizing components can accelerate the design and development process, freeing up time for product teams to focus on solving high-level problems instead of execution details.

Components are the cornerstone of modern product design, paving the way for a world full of unique experiences, streamlined workflows, and the next generation of platforms.
