Javascript - alert(“zoo”>“house”) returns true

Question

alert(\"zoo\">\"house\") returns true.
Could anyone explain me why?

Answer 1

Because it does a lexical comparison, and z is greater than h (that is, the code unit for z has a higher numeric value than the code unit for h). If both strings started with the same character, the second character would be checked, and so on. Full details in turgid detail in the spec.
