Maximum length of variable name in JavaScript

Question

What is the maximum length of a variable name in JavaScript?

Answer 1

I've tried the example above, x10 the amount of characters, then again, then again, then again.

When the variable length is of 513k characters, my Notepad++ is slugging along like a snail. Yet when I managed to save the file and run it locally, the alert appears without any delay.

Tested on: Chrome 19.0.1084.52, IE9, FireFox 11.0, Safari 5.1.5, Opera 11.62

Since JSBin only allows a maximum of 65535 characters within the tags, I only managed to create a page with a 32.5k length variable: http://jsbin.com/ukunow/10
