A lightweight and fast standalone JavaScript number formatter, version 1.2.0. It supports standard number formatting masks like '#,##0.00', custom grouping and decimal symbols, auto-rounding, and prefix/suffix (with restrictions). The library is less than 1.2 KB minified and has no dependencies. It is available as an npm package and via Bower, with UMD support (AMD, CommonJS, global). Key differentiators: tiny footprint, simple API, and flexible mask syntax. Not intended for scientific notation or date formatting.
