    Finds all the indexes of a substring in a given string.

    const indexOfSubstrings = function* (str: string, searchValue: string) {
      let i: number = 0;
      while (true) {
        const r: number = str.indexOf(searchValue, i);
        if (r !== -1) {
          yield r;
          i = r + 1;
        } else return;
      }
    };
