Hi, i am trying to find a good JS character countdown script that i can use to count down the characters remaining in a text area field that i am using on my site.

I have done a lot of searching on google but a lot of them seem to have very long scripts and others scripts are over 6 years ago.

Can someone recommend a good, robust character countdown timer that works very well and does not require a lot of resources when it is running. I was hoping to find something similar to the twitter script (please see below)
