Jiffies

JEFRi Jiffies are a number of "common" utilities for JavaScript/TypeScript pulled from and inspired by other programming languages, and common base tools missing or inconsistent between DOM and Node runtimes.

• assert - common runtime assertions.
• context - JavaScript implementation of the Python [with][pywith] statement.
• display - TypeScript implementation of the Rust [Display][rustdisplay] trait.
• equal - JavaScript deep equality checkers, including TS type checking.
• flags - JavaScript flag, environment, and configuration loader.
• log - JavaScript implementation of a [log4j][log4j]-alike logger.
• result - JavaScript implementation of Rust's [Option][rustoption] and [Result][rustresult] types.
• loader.mjs - Node 16.x typescript-transpiling module loader.

Jiffies also includes several microframeworks.

• dom - a tiny DOM functional library.
• pico - a copy of PicoCSS.
• scope - JavaScript testing microframework.
• server - Node HTTP Server & middleware.
