idle-bignum
idle-bignum is a very small, fast, big number library for incremental and idle games in javascript.
Introduction
If you are looking for a simple solution to handle big numbers above the javascript limit of 1.79E+308 (MAX_VALUE) for your next incremental game then idle-bignum is what you need.
Note: The class names powers of ten using the Conway-Wechsler System (e.g. 10^261 is named sexoctogintillion).
I have used this class in the incremental game Idle Brainz. A demo is available here.
