On a slightly different note, another good way (which Crockford also
suggests) is instead of using parseInt(), coerce the string into
number by using +'08'. This will give you the number 8.
Note that in your case this may not be what you want since it gives a
number, not an integer. This is fine if you know your string contains
a round number, but not if your string can contain a decimal point.
e.g. +'08.5' will give you the number 8.5.
If you ever use this in a calculation of some sort, it's also good to
put parens around your coerce. For example:
var x = something + (+'08') + whatever;
Cheers,
