Document: createRange() method
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
The Document.createRange() method returns a new
Range object whose start and end are offset 0 of the Document
object on which it was called.
The created Range object.
js
const range = document.createRange();
range.setStart(startNode, startOffset);
range.setEnd(endNode, endOffset);
Once a Range is created, you need to set its boundary points before you
can make use of most of its methods.
