Simplify this JS using the “#” tags
I am extending code (associated with Telerik MVC) and came across a confusing section:
<img src="# if (sessionStorage.getItem(ImageId)) { # data:image/png;base64,#:sessionStorage.getItem(ImageId)# # } else { # @(Url.Content("~/Pictures/"))#:ImageId# # } #" />
I know what this is doing -- It retrieves an image from session state or assigns it to one from a /Pictures folder.
I need to extend this logic, but find it very confusing with the above structure. I am not familiar with it, and cannot find anything online to explain the "#" character that is in use. I also cannot find how to restructure it so it's more legible, especially if I extend, as right now everything is on one line. Any advice?

it appears that this is not JavaScript but some sort of macro that is being parsed. the#are probably at the beginning of each line on the server code, before the newlines are stripped on the client side.

in fact, this is actually documented: docs.telerik.com/kendo-ui/framework/templates/overview. Particularly: > "3. Execute arbitrary JavaScript code:# if (true) { # ... non-script content here ... # } #."
