Core.ts is a library of TypeScript utility function and classes, including array and string helpers, function wrappers and event classes. It was developed for Mathigon.org, an award-winning mathematics education project.


  • Function wrappers for caching and throttling (cache(), throttle())
  • Array generation (tabulate(), repeat(), list())
  • Array utilities (total(), flatten(), chunk(), intersect(), …)
  • String utilities (toCamelCase(), isPalindrome(), autoCorrect(), …)
  • Event Target class, supporting .on(), .off() and .trigger() methods
  • Color parsing, conversion and interpolation
  • Misc utilities (uid(), isOneOf(), …)


First, install Core.ts from NPM using
``npm install @mathigon/core``
Now, simply import all functions and classes you need, using
import {tabulate, toCamelCase, EventTarget} from '@mathigon/core'
