For most simple cases, I use a prefix of a unary plus to convert
strings to numbers. It's short. It's easy to read once you're used to
doing it. I haven't tested the speed, but it may be faster as well.
>>> typeof("1");
"string"
>>> typeof(+"1");
"number"

Yep - parseInt() or parseFloat().
When you are pulling data from HTML you will get something like "55"
rather than 55 (notice the quotes). So then doing something like this:
var count = $("#mydiv").text() + 100;
WOuld result in count being set to "55100" (assuming the div had 55 in it).
