For the record: Yes, typescript-language-server uses 
ParameterInformation documentation. You can use this this source 
code to check it out. Just move the cursor to the first 
"undefined".

#+begin_src typescript
/**
 ,* Returns the average of two numbers.
 ,*
 ,* @param x - The first input number
 ,* @param y - The second input number
 ,* @returns The arithmetic mean of `x` and `y`
 ,*
 ,* @beta
 ,*/
function getAverage(x: number, y: number): number {
  return (x + y) / 2.0;
}

getAverage(undefined as number, undefined as number);
#+end_src


The value of this parameter's documentation will be:

#+begin_src emacs-lisp
(:kind "markdown" :value "- The first input number")
#+end_src
