JSdoc how to tell that a function returns the same type as a parameter
in C# you would write
T RandomFrom< T >( List< T > list )
return list[ ( int ) Math.Floor( new Random().Next() * list.Count ) ];
How should I do the same when documenting a JS function?
I tried:
/**
* @type * T
* @param T list
* @returns T
*/
function randomFrom ( list )
return list[ Math.floor( Math.random() * list.length ) ];
But VS Code tells me randomFrom(list: any): any and I'd like it to be something like randomFrom(list: <T>): <T>. How do I achieve that? Putting the T inside <> makes it an arrow function.

Have you tried combining with a@typedefJSDoc block?
