  3. If both px and py are Strings, then
    ...
  4. Else,
    a. Let nx be ? ToNumeric(px). Because px and py are primitive values evaluation order is not important.
    b. Let ny be ? ToNumeric(py).
    c. If Type(nx) is Type(ny), return ? Type(nx)::lessThan(nx, ny).

  sec-numeric-types-bigint-lessThan
  BigInt::lessThan (x, y)

    The abstract operation BigInt::lessThan with two arguments x and y of BigInt type returns true if x is less than y and false otherwise.
