What units (KB, MB, GB...) does this support?

The pretty-bytes library supports multiple unit systems depending on the options you use:

Byte Units (default) [index.js:L1-L9]:

• B, kB, MB, GB, TB, PB, EB, ZB, YB

Binary Byte Units (when binary: true) [index.js:L12-L20]:

• B, KiB, MiB, GiB, TiB, PiB, EiB, ZiB, YiB

Bit Units (when bits: true) [index.js:L23-L31]:

• b, kbit, Mbit, Gbit, Tbit, Pbit, Ebit, Zbit, Ybit

Binary Bit Units (when both bits: true and binary: true) [index.js:L34-L42]:

• b, kibit, Mibit, Gibit, Tibit, Pibit, Eibit, Zibit, Yibit

The choice of unit system is determined by the bits and binary options passed to the prettyBytes() function [index.js:L140-L142]. By default, it uses the base-10 byte units (SI prefix), which follows the kilobyte standard (1 kB = 1000 B) rather than the binary standard (1 KiB = 1024 B).
