How it got here

2012 · Project rename and infrastructure cleanup

The project was renamed from FunJS to FunScript, accompanied by a comprehensive cleanup of obsolete code, legacy package references, and outdated testing frameworks. The build system was modernized to use Paket for dependency management, and the repository structure was updated with new build scripts and CI configuration.

2014–2015 · Core architecture and ecosystem expansion

This period focused on significantly refactoring the FunScript compiler into a modular, component-based architecture to improve JavaScript generation. Concurrently, the project expanded its ecosystem by introducing new packages for data access (FunScript.Data), reactive streams (FunScript.Rx), and TypeScript interop (FunScript.TypeScript). These changes were supported by comprehensive test coverage and practical examples demonstrating web and mobile development capabilities.

About this page

  • The description of this project is derived from its own commit history, not from its README.
  • The score is its highest published measurement, taken on 1 August 2026 at a pinned commit. It is not a live figure and does not change until the project is measured again.
  • Measured at commit 941d28b407 — the exact code this score is about.
  • Scored under rubric rubric-2026.08.18. Score the same commit under that rubric and you get the same number.
