Numeric comparison

Numeric comparison using JavaScript's greater-than and less-than operators is fairly intuitive. As mentioned, your operands will be coerced first to their primitive representations, and then coerced a second time, explicitly, to a number. For cases where both operands are numbers, the result is entirely intuitive:

123 < 456; // => true

And for NaN and Infinity, the following assertions can be made:

Infinity > 123; // => trueInfinity >= Infinity; // => trueInfinity > Infinity; // => falseNaN >= NaN; // => falseNaN > 3; // => falseNaN < 3; // => false

If one operand has a primitive representation that is not Number, then it will be coerced to Number before comparison. If you were to accidentally pass Array as an operand to ...
