Progress bar is a visual indicator used to display the completion status of a task or process, such as a form fill-up or system operation. It gives users a clear sense of duration and expectation, aiding in their patience while they they go through the journey.

Progress bars can be determinate, showing a specific completion percentage, or indeterminate, used when the completion time is unknown. By providing visual feedback on the progress of operations, this component enhances user experience by managing expectations, reducing uncertainty, and keeping users informed about the application's status.
