The pretty-bytes library supports multiple sets of units depending on the options you use:
Standard byte units (SI Prefix) — used by default:
B, kB, MB, GB, TB, PB, EB, ZB, YB
[index.js:L1-L9]
Binary byte units — when binary: true option is set:
B, KiB, MiB, GiB, TiB, PiB, EiB, ZiB, YiB
[index.js:L11-L19]
Bit units (SI Prefix) — when bits: true option is set:
b, kbit, Mbit, Gbit, Tbit, Pbit, Ebit, Zbit, Ybit
[index.js:L21-L29]
Binary bit units — when both bits: true and binary: true options are set:
b, kibit, Mibit, Gibit, Tibit, Pibit, Eibit, Zibit, Yibit
[index.js:L31-L39]
The function automatically selects the appropriate unit array based on your options and scales the input number accordingly [index.js:L139-L141].
