Faster jQuery With Category Theory
summary
Shows that exposing the DOM-manipulating core of jQuery methods and composing them into a single pass reduces loops and gives measurable wins — roughly 5–10% on a removeAttribute example and similar gains in a jQuery Mobile helper. Implements a compose function that composes underlying DOM functions, a map-based functor that maps DOM→jQuery methods, and a small library that emits a proxy warning when chains can be squashed. Works in small examples; needs more real‑world testing and careful partial application.
