The clear() method of the HighlightRegistry interface removes all the Highlight objects registered in the HighlightRegistry.
HighlightRegistry is a Map-like object, so this is similar to using Map.clear().
js
clear()
None (undefined).
The code snippet below registers two highlight objects in the registry and then clears the registry:
js
const customHighlight1 = new Highlight(range1, range2);
const customHighlight2 = new Highlight(range3, range4, range5);
CSS.highlights.set("custom-highlight-1", customHighlight1);
CSS.highlights.set("custom-highlight-2", customHighlight2);
console.log(CSS.highlights.size); // 2
CSS.highlights.clear();
console.log(CSS.highlights.size); // 0
