0.15.0

Changelog

Features

• #570 Add microtask scheduling helpers with native queueMicrotask, Promise, and timer-backed fallbacks
  • New functions: scheduleMicrotask, hasQueueMicrotask, getQueueMicrotask, setMicroTaskFallbackOptions
  • New public types: ScheduleMicrotaskFn, MicroTaskOptions
  • Extends microtask support by providing cancellable microtasks via ITimerHandler, plus fallback ordering to run microtasks before queued timers when using the timer-backed implementation
  • Provides runtime parity across all supported environments by using native queueMicrotask when present, Promise-backed scheduling when available, and a timer-backed microtask queue otherwise
• #573 Add nextTick scheduling support and new helper exports
  • New timer/runtime functions: scheduleNextTick, getProcessNextTick, hasProcessNextTick, setNextTickFallbackOptions
  • Uses native process.nextTick in Node runtimes when available, while providing equivalent nextTick behavior in browser and worker runtimes via Promise and timer-backed fallbacks
  • Adds shared queue logic and callback-argument support across microtask and nextTick scheduling
  • Adds arrConcat as a dedicated array helper and fnBindArgs as a dedicated function helper
  • Improves function binding typing with exported BoundFunction and updated signatures for fnBind / fnBindArgs
• #574 feat(iterator,array): add iterator collection helpers, split helper modules, and align collection membership semantics
  • Added new iterator helpers: iterMap, iterFilter, iterTake, iterReduce, iterSome, iterEvery, iterToArray, iterUnion, iterIntersection, iterDifference
  • Added arrToMap helper in the array module and moved callback/type declarations into iterator/types
  • Refactored iterator helper implementation/tests into per-function files and updated root exports
  • Added NaN regression coverage and switched iterator set-operation membership checks to arrIncludes semantics for parity with array helpers
• #576 Refactor timer microtask/nextTick shared types and environment helpers, with expanded fallback coverage
  • Moved MicrotaskFn and ScheduleMicrotaskFn to helpers/types and updated timer internals to consume shared type definitions
  • Moved getQueueMicrotask and hasQueueMicrotask to helpers/environment, updated root exports, and aligned scheduleNextTick fallback resolution to prefer queueMicrotask when available
  • Added internal microtaskQueue scheduler helper wiring and expanded tests for queue fallback behavior, Promise ordering, and no-Promise edge cases

Bug Fixes

• #568 Rolldown INVALID_ANNOTATION warnings caused by non-canonical PURE annotation spacing in generated output
  • #569 Add generated-chunk PURE annotation normalization so spaced forms are rewritten to canonical (/*#__PURE__*/ / (/*@__PURE__*/ in rollup output
  • #575 Add packaged artifact validation for PURE annotation spacing and update normalization tolerance, with per-file logging while scanning lib/bundle and lib/dist

New Contributors

• @hrithik-infinite made their first contribution in #569

0.14.0

Changelog

Features

• #525 feat(array): add new array helpers and array-like detection
  • New helpers: isArrayLike, arrUnique, arrCompact, arrFlatten, arrGroupBy, arrChunk and export previously missed isArrayLike
• #527 feat(string): add strReplace and strReplaceAll helpers with refactored internal replacements
• #528 feat(string): add strCapitalizeWords helper
• #529 / #530 feat(string): add strTruncate, strCount, strAt, and strMatchAll helpers with shared literal regex helper
• #533 feat(array): add arrFlatMap with ES5 polyfill support
• #535 docs(types): add typing utilities for v0.14.0 and expand TSDoc examples
• #536 feat: add isAsyncIterable and isIntegerInRange type/value inspection helpers
• #543 feat(string): add strStartsWithAny, strEndsWithAny, strWrap, strUnwrap, and strNormalizeNewlines helpers
• #564 feat(object): add new object utility helpers and harden defaults against prototype pollution
  • New helpers: objPick, objOmit, objPickBy, objOmitBy — property selection and omission with typed overloads
  • New helpers: objMapValues — create a new object with values transformed by a mapper function
  • New helpers: objMergeIf, objDefaults — conditional merge and shallow defaults (similar to Lodash _.defaults) hardened against prototype pollution
  • New helper: objDiff — shallow diff returning only changed/added keys from a modified object vs a base
  • New helpers: forEachOwnKey, forEachOwnKeySafe — iteration over both string and symbol keys (existing forEachOwnKeySafe was string-only)
  • New helper: objForEachKeySafe — safe string-key iteration that filters __proto__, constructor, prototype
  • Extended isUnsafeTarget coverage to TypedArrays, ArrayBuffer, DataView, WeakRef, FinalizationRegistry

Security Issue

• CVE-2026-46681 Prototype Pollution in objDeepCopy/objCopyProps via for...in without hasOwnProperty
  • Also affected setValueByKey and setValueByIter
  • #565 feat: add prototype-pollution guards and array key helpers

Bug Fixes

• #558 Fix ES2015 built-in type errors in consumers by adding lib reference directive to published declarations
  • Consumers using "lib": ["ES5", "DOM"] (or omitting lib) received Cannot find name 'Symbol' / Cannot find name 'Iterator' errors because the published .d.ts exposed ES2015 types without declaring the dependency
  • Added /// <reference lib="es2015" /> to the source entry points (index.ts, polyfills.ts) and a new post-processing script (lib/scripts/setTsReferences.js) that prepends the directive to the api-extractor bundled output (api-extractor strips these directives from its rollup)
  • Added "lib": ["ES2015", "DOM"] to all library and test tsconfig files for consistent compile-time validation
  • Net effect: consumers no longer need to add "ES2015" to their own tsconfig.json lib settings
• #561 Bug: Falsy thisArg (0, '', false) overridden in arrForEach/iterForOf/objForEachKey
  • #566 Fix falsy thisArg (0, '', false) being overridden in arrForEach, iterForOf, objForEachKey
• #562 Fix thisArg binding in polyArrFindIndex / polyArrFindLastIndex polyfills

Repository Improvements

• #549 Drop Node.js 16 from CI matrix and add Node.js 24
• #552 Upgrade Grunt devDependency to v1.6.2
• #554 Add funding metadata to published package manifests
• #556 Add release PR instructions to Copilot instructions

0.13.0

Changelog

Features

• Added comprehensive encoding and decoding functions for multiple formats:

  • Base64 Encoding/Decoding: encodeAsBase64() and decodeBase64() with native fallbacks and ES5 polyfill support
  • URL-Safe Base64: encodeAsBase64Url() and decodeBase64Url() for safe Base64 encoding in URLs (replaces + with -, / with _, removes padding)
  • Hexadecimal Encoding/Decoding: encodeAsHex() and decodeHex() for hex string conversion
  • URI Encoding/Decoding: encodeAsUri() and decodeUri() for URL component encoding
  • All encoding functions include internal polyfills (_encodeBase64Polyfill, _decodeBase64Polyfill) for ES5 environment compatibility
  • Consistent handling of null/undefined values across all encoding functions

• Enhanced createCustomError() with superArgsFn parameter:

  • New optional superArgsFn parameter allows custom transformation of constructor arguments before passing to base class
  • Enables support for different argument orders and subsetting arguments passed to the base class constructor
  • Useful for creating custom error subclasses with different constructor signatures than their base classes
  • Example: HTTP error with (statusCode, message) signature can map to base Error(message) constructor

Performance Improvements

• Improved performance of worker test execution
  • Optimized test runner for faster execution in web worker environments
