What small utility packages need: predictable null behavior, path handling, tests, and clear API boundaries.

Utility packages look simple until they touch undefined paths, arrays, nested values, and user expectations. I prefer explicit path parsing, predictable return values, chainable APIs only where they improve readability, and tests around null, undefined, array, and type-coercion behavior.

const result = compareGuard(user)
  .path("profile.age")
  .greaterThanOrEqual(18)
  .and("account.status")
  .equals("active");
