remove n chars from start or end of a string

[lemongrassnginger]

Is there a method for removing n characters from the left or right of a string? Similar to left and right but providing the number of characters to remove rather than keep?

I've had a look but I can't seem to come up with a better way than the following, which works but is a bit long-winded for a string processing library:

// remove the last two characters
s = S('abcde')
s.left(s.length - 2).s
// "abc"

Does it solve?

var s = 'abcde';
s.substr(0, s.length - 2) // abc --- remove 2 chars from right
s.substr(2) // cde --- remove 2 chars from left

Sure does, however my point is given this is a string processing library, there should be dedicated methods for this. For the remove two characters from right example, you need to define s then reference it twice - once from the method invocation and then another in s.length to calculate the substring length. It's not a big deal, just an observation.

Got it. So maybe a .removeRight(5) or .removeLeft(3) would make more sense, right?
