Is there something similar to C# regions in JavaScript? Visual Studio 2017

I am doing work for somebody who would like their JavaScript library organized into categories: CRUD functions, Form functions, etc. They really like the utility of regions in C# and are asking for this in their JavaScript file. Any suggestions? I am using Visual Studio 2017 and Team Foundation Server.

Answer

Select the code you want to compress. Press Ctrl + M + H. That code will now be collapsible. For readability, comment above the “region” to give it a name.
