I have the following TS code:

const input: Array<string | number> = [3, "a", "a", "a", 2, 3, "a", 3, "a", 2, 4, 9, 3];

const convertArrayToMap = (inputArray: Array<string | number>): Map<string | number, number> => {
  const convertedArray: Array<[string | number, number]> = inputArray.map((item) => [item, 0]);

  return new Map<string | number, number>(convertedArray);
};

const input: Array<string | number> = [3, "a", "a", "a", 2, 3, "a", 3, "a", 2, 4, 9, 3];

const convertArrayToMap = (inputArray: Array<string | number>): Map<string | number, number> => {
  const convertedArray: Array<[string | number, number]> = inputArray.map((item) => [item, 0]);

  return new Map<string | number, number>(convertedArray);
};

I'm trying to take an array of strings and numbers as an input and convert it to a map. I got this code working, but it took me almost an hour and a half and seems incredibly convoluted for the task. Surely there's a better way?
