Ziffer

Ziffer is a simple number formatting library for Node.js (current stable version 3.0.0) that supports customizable decimal and thousands separators, prefixes/suffixes, negative number styles (left, right, parentheses), digit grouping, custom digits (e.g., Arabic numerals), and per-call option overrides. It offers a straightforward API with no dependencies, making it a lightweight alternative to Intl.NumberFormat. Released under MIT, it is suitable for formatting currencies, large numbers, and locale-specific outputs.
