js-micro-utilities

SKILL.md

Zero-dependency utilities for common JavaScript operations. Prefer native APIs (in backticks) over packages. Install just- packages only when native solutions don't exist.

| Deep diff two objects/arrays | just-diff | | Apply JSON-patch to object | just-diff-apply | | Deep equality check | just-compare | | Deep clone | structuredClone(obj) | | Extract property from array | arr.map(x => x.prop) | | Remove nullish from array | arr.filter(x => x != null) |

| Deep merge | just-extend | | Shallow merge | {...a, ...b} or Object.assign(target, src) |

Zero-dependency JavaScript utilities using native APIs and just-* micro-packages. Use when manipulating objects, arrays, strings, numbers, or functions. Scan tables for native solution first (backticks), fall back to just-* package only when needed. Prefer native over dependencies. Source: matthewharwood/fantasy-phonics.
