 For example, `true` becomes `1` and `false` becomes `0`. `undefined` becomes `NaN`, but (curiously) `null` becomes `0`.
 
-`ToNumber` for a `string` value essentially works for the most part like the rules/syntax for numeric literals (see Chapter 3). If it fails, the result is `NaN` (instead of a syntax error as with `number` literals). One example difference is that `0`-prefixed octal numbers are not handled as octals (just as normal base-10 decimals) in this operation, though such octals are valid as `number` literals (see Chapter 2).

 **Note:** The differences between `number` literal grammar and `ToNumber` on a `string` value are subtle and highly nuanced, and thus will not be covered further here. Consult section 9.3.1 of the ES5 spec for more information.

-The algorithm first calls `ToPrimitive` coercion on both values, and if the return result of either call is not a `string`, then both values are coerced to `number` values using the `ToNumber` operation rules, and compared numerically.
