Q: What are the different types of progress bars in JavaScript?

Linear (horizontal bar with width %), circular (SVG ring with stroke-dashoffset), and stepped (discrete steps with active states). Also striped (animated stripes) for indeterminate progress.

Q: How do you build a circular progress bar with SVG in JavaScript?

Use two SVG circles. The background circle has a gray stroke. The progress circle has stroke-dasharray set to the circumference (2 * PI * radius) and stroke-dashoffset set to circumference - (percent/100 * circumference). Rotate -90 degrees.

Q: When should you use a circular vs linear progress bar?

Use circular for loading states, countdown timers, and dashboards (compact, visual). Use linear for file uploads, downloads, and task completion (shows proportion clearly). Use stepped for multi-step forms.
