Salsa: declaring function types using @typedef is not working

[mohsen1]

Not sure if this is the right syntax for declaring a function in JSDoc but if it is, it's not working.

TypeScript Version: 2.9

Search Terms:
@typedef function Salsa
Code

/**
 * @typedef {Function} SortCallback
 * @param {number} a
 * @param {number} b
 * @returns {number}
 */

 /** @type {SortCallback} */
 var fn = function(a, b) { return 1};

 [1,2,3,5].sort(fn);

Expected behavior:
No Error

Actual behavior:

index.js(11,17): error TS2345: Argument of type 'Function' is not assignable to parameter of type '((a: number, b: number) => number) | undefined'.
  Type 'Function' is not assignable to type '(a: number, b: number) => number'.
    Type 'Function' provides no match for the signature '(a: number, b: number): number'.

I do not think this is a supported use of typedef. we should just support @callback for such cases, that is tracked by #7515

Thanks! I think @callback is the right syntax as well
