## What it is
Numeral.js is a JavaScript library for formatting and manipulating numbers, supporting formats like currency, percentages, bytes, time, and abbreviations, with locale support and custom format plugins. It works in the browser and Node.js.

## Use cases
- format numbers with thousands separators in javascript
- display currency values in the browser
- format percentages and bytes in a web app
- parse number strings like '1,000' into values
- localize number formatting for different languages

## When to choose
- you need lightweight number formatting in browser or Node.js
- you need locale-aware number, currency, or percentage formatting
- you want extensible custom number formats

## When to avoid
- you need arbitrary-precision decimal math
- you need full date/time formatting (use a date library)
- you need actively developed alternatives like Intl.NumberFormat

## Facets
- artifact type: library
- maturity: maintenance
- function: serialization, internationalization
- domain: web-development, frontend, developer-tools
- platform: browser, cross-platform
- tags: number-formatting, currency, percentages, javascript, nodejs
