how do i get the numeric representation of a character in javascript?

Question

I'd like to get a javascript numeric representation for a letter to do some relative manipulation i.e. in pseudocode to conduct an operation like 'a'.getNumberRep - 'b'.getNumberRep.

Best way to do this in js?

what do you mean exactly by "numeric representation" ? Transforming "1" to 1 ? Unicode value ? Alphabetic value ? — Valentin Rocher, Jan 31 '10 at 12:51
