a TypeScript and deno problem

// The problem. Save this as x.ts, then call deno run x.ts
// You get the error , shown in the other pane
// deno wants u to add typescript types, but the problem is, can't do it unless perhaps most of the types is any, or u mod the code so it have if statement to catch impractical errors such as out of bound index, empty string, etc
// The question is, how do u add type declaration, without changing ur code to add silly impractical error catching

const fCharStrToId = ((x) => x.codePointAt(0));
const fCharIdToStr = ((x) => (String.fromCodePoint(x)));
console.log(fCharStrToId("😂"));

;; 2022-04-03 There's a new notation for key, based on finger.
;; For example the qwerty e key is Lp2p1.
;; The notation is like this: [left or rigt hand][column number][row number].
;; L means left hand, R means right hand
;; Column position, pointing finger is 1, index is 2, ring finger is 3, pinky is 4, and so on in that direction. Thumb is 0. In the thumb direction is -1, -2 etc.
;; Row position, home row is 0. Above is 1, below is -1.
;; Positive number are written with p in front. Eg p1, p2. Zero is p0. Negative can be written with n in front, eg n1, n2.
;; This system is a notation system for keyboard physical layout, which also indicates associated finger for that key.
;; The advantage is that it's a logical system, not based on arbitrary table lookup.
;; Qwerty, dvorak, etc can then be mapped to this logical system.
