This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The Selection.isCollapsed read-only property returns a Boolean which indicates whether or not there is currently any text selected; That is to say that the selection's start and end points are at the same position in the content.

Keep in mind that a collapsed selection may still have one (or more, in Gecko) Ranges, so Selection.rangeCount may not be zero. In that scenario, calling a Selection object's getRangeAt() method may return a Range object which is collapsed.

Syntax

bool = sel.isCollapsed
