How to display the folder name of a file ? Also how to use the new source option - Dataview (JS pages) ?

[pravin-d]

I have Projects folder for each project. Inside each of the folders there is a file that tracks tasks for that particular project. When I use db folder on Main Projects folder, it just gives me a list of file all with similar name. So in addition to displaying the name of file I want also get information regarding the folder in which it is present.
One solution would be to use some frontMatter per file. This would however would not work if I end up nesting more, etc.
Another solution would be probably to use Dataview with JS pages. However there is no documentation regarding the same. The documentation only talks about Dataview query and not about dataviewJS
Any help would be really appretiated
Thank you
