JS circular progress bar gradient color

Quick answer：

A circular progress bar with gradient color in JavaScript typically involves creating a circular shape and then using CSS gradients to fill it with colors that represent progress. This can be achieved by using SVG (Scalable Vector Graphics) for the circular path and CSS for the gradient fill. Techniques like using SVG's `` element with a `stroke-dasharray` and `stroke-dashoffset` to simulate a progress bar, and applying a linear gradient to the stroke, can be used to create an appealing visual effect.
