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

Question

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

Answer 1

For VS 2019, Microsoft has fully implemented regions for Javascript, they work exactly they way they work in C#, only, you have to preface the beginning and end of the regions as comments, for example:

//#region My Region
function foo(){
  *//code*
}
//#endregion

For anything prior to VS 2019, See Michael Drum's answer. His shortcut also works in VS 2019.
