The Range() constructor returns a newly created Range object whose start and end are offset 0 of the global document object.
new Range()None.
In this example we create a new range with the Range() constructor, and set its beginning and end positions using the Range.setStartBefore() and Range.setEndAfter() methods. We then select the range using window.getSelection() and Selection.addRange().
<p>First paragraph.</p>
<p>Second paragraph.</p>
<p>Third paragraph.</p>
<p>Fourth paragraph.</p>const paragraphs = document.querySelectorAll("p");
// Create new range
const range = new Range();
// Start range at second paragraph
range.setStartBefore(paragraphs[1]);
// End range at third paragraph
range.setEndAfter(paragraphs[2]);
// Get window selection
const selection = window.getSelection();
// Add range to window selection
selection.addRange(range);
