makeCharMap.ts

// makeCharMap takes two strings and creates a mapping between characters at the
// same position, like Unix tr or Python string.translate. We don't worry about
// undefineds, since the caller of Map.get has to check for undefined anyways
// (for the case where they pass in an input char that's not in the map).
export const makeCharMap = (inChars: string, outChars: string) =>
  new Map(zip(inChars.split(""), outChars.split("")));
