Damm check digit algorithm
Zero-dependency CUSIP validator. Validates 9-character CUSIP identifiers using the Modulus 10 Double Add Double check digit algorithm.
Collection of check digit algorithms implemented in JavaScript
Validates New Zealand tax numbers (IRD)
JWA implementation (supports all JWS algorithms)
Returns the check digit for all GS1 Keys requiring a Modulo 10 check digit, i.e. Global Trade Item Number (GTIN) in all applicable formats, i.e. GTIN-8, GTIN-12, GTIN-13, GTIN-14, Global Location Number (GLN), Serial Shipping Container Code (SSCC), Global
Implementation of JSON Web Signatures
Fast 2D concave hull algorithm in JavaScript (generates an outline of a point set)
This package includes two Angular directives. The digitOnly directive only allows numbers in the input box when typing, pasting or drag/dropping. The mask directive checks the input pattern attribute.

An implementation of the Unicode Line Breaking Algorithm (UAX #14)
A JS library for finding optimal label position inside a polygon
A point in polygon based on the paper Optimal Reliable Point-in-Polygon Test and Differential Coding Boolean Operations on Polygons
Convert shorthand hex color codes into full
graph algorithm
A pure JS implementation of the structured clone algorithm (or at least something pretty close to that)
Detect the indentation of code
Simple “Least Recently Used” (LRU) cache
Sniff the encoding from a HTML byte stream
