Highlight: add() method
Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

Highlight is a Set-like object, so this is similar to using Set.add().

const range2 = new Range();
highlight.add(range1).add(range2);
console.log(highlight.size); // 2
