v8.0.0

Breaking

• Require Node.js 22 faf7003

New

• Add finiteNumber predicate 63be5c0
• Add nonNegativeNumber predicate 63be5c0
• Add positiveInteger predicate 63be5c0
• Add negativeInteger predicate 54fc094
• Add nonNegativeInteger predicate 54fc094
• Add arrayOf predicate factory 54fc094
  • Returns a type guard that checks if every item in an array matches the predicate. Useful for composing with other methods.
• Add oneOf predicate factory 54fc094
  • Returns a type guard that checks if a value is one of the given values. Best used with as const for precise type narrowing.

Fixes

• Fix isEmptyObject and isNonEmptyObject incorrectly accepting functions and arrays 3b40955
• Fix isNumericString incorrectly accepting strings with surrounding whitespace 47415dc
• Fix isInRange silently returning false when range contains NaN (now throws) ac46b54
• Fix isEnumCase incorrectly accepting numeric enum key names cb4ee0e
• Fix numeric type guards (isInteger, isEvenInteger, isOddInteger, isSafeInteger, isPositiveNumber, isNegativeNumber, isInfinite, isNan, isValidLength) narrowing the false branch to never 13febb6
  • These now use branded types so that if (!is.integer(n)) { ... } keeps n as number instead of never
