Hi, original author here. When I started out I wasn't trying to solve a problem. I was exploring a concept I was curious about. But in the end, we (me and a colleague) ended up building it into our WYSIWYG HTML editor as an alternative to the browsers execCommand editing API. When editing rich text, an API that is build around ranges for everything is a perfect fit.

The editor (https://simplyedit.io/) converts a contenteditable area's content to hope, we apply some markup (annotations) and convert the result back to HTML. I wrote the Hope-HTML conversion routine once, and all the range based manipulations are now one-liners instead of treewalking horror shows.
