If both px and py are Strings, then 9 ... 10 4. Else, 11 a. Let nx be ? ToNumeric(px). Because px and py are primitive values evaluation order is not important. 12 b. Let ny be ? ToNumeric(py). 13 c. If Type(nx) is Type(ny), return ? Type(nx)::lessThan(nx, ny). 14 d. Assert: Type(nx) is BigInt and Type(ny) is Number, or if Type(nx) is Number and Type(ny) is BigInt. 15 e. If x or y are any of NaN, return undefined. 16 f. If x is -∞, or y is +∞, return true. 17 g. If x is +∞, or y is -∞, return false. 18 h.
