v1.51.0

Compare Source

Released on August 17th, 2026.

• Added the es-toolkit/bigint entrypoint: bigint counterparts of the math
  functions (sum, sumBy, max, min, maxBy, minBy, clamp, inRange,
  median, medianBy, percentile, range, rangeRight), kept separate so
  the number implementations stay unchanged. ([#​1966])

• Added dedent, which removes common leading whitespace from template strings. ([#​1679])

• Added deepFreeze for recursively freezing objects. ([#​1680])

• Added mapValuesAsync and mapKeysAsync. ([#​1544])

• Added toPascalCaseKeys, toKebabCaseKeys, and toConstantCaseKeys,
  completing the object key casing family. ([#​1984])

• Exported the ToCamelCaseKeys, ToPascalCaseKeys, ToSnakeCaseKeys,
  ToKebabCaseKeys, and ToConstantCaseKeys types. ([#​1651])

• Added a preserveArrays option to flattenObject. ([#​974])

• Fixed retry to pass the last error to the delay callback ([#​1759]) and to
  throw the last attempt's error without applying a final delay ([#​1901]).

• Fixed mergeWith and toMerged to handle mixed array/object types
  consistently with merge. ([#​2026])

• Fixed pullAt to remove the correct elements with negative indices. ([#​1613])

• Fixed at, pullAt, orderBy, and sortBy to accept readonly arrays. ([#​2016])

• Moved limitAsync from the array to the promise category. ([#​2022])

• Included the NOTICE file in the published npm and JSR packages. ([#​2020])

The following bring es-toolkit/compat closer to Lodash. Behavior for the affected
edge cases now matches Lodash, so results may differ if you relied on the previous output.

• Added entries and entriesIn. ([#​1874])

• Fixed compat/isMatch and compat/isMatchWith to handle object source
  patterns against primitive and non-plain-object targets like Lodash. ([#​1432])

• Fixed compat/set to block constructor.prototype paths, preventing
  prototype pollution. ([#​1904])

• Fixed compat/find to respect array-like length ([#​1958]) and to convert
  fromIndex to an integer ([#​1961]), and compat/indexOf to convert
  fromIndex to an integer when searching for NaN ([#​1951]).

• Fixed compat/orderBy to resolve unresolved deep paths and nullish elements
  to undefined ([#​2010]), to exclude the length property from array-like
  values ([#​2002]), and to read the criterion property from primitive values ([#​1903]).

• Fixed compat/toPath to split unquoted dotted keys inside brackets. ([#​1899])

• Fixed compat/omit to treat a key array as a single deep path. ([#​1902])

• Fixed compat/map to make the iteratee optional with an identity default. ([#​1928])

• Fixed compat/size to count combined Unicode symbols as single characters. ([#​1900])

• Fixed compat/intersectionBy to support number, object, and nullish iteratee
  shorthands ([#​1993]), and compat/intersectionWith to apply the comparator
  when deduplicating the first array ([#​1953]).

• Fixed compat/difference, compat/differenceBy, compat/uniqBy, and
  compat/unionBy to normalize -0 to 0. ([#​2007])

• Fixed compat/maxBy and compat/minBy to skip nullish iteratee values ([#​1927]),
  and compat/meanBy to skip undefined values when averaging ([#​1978]).

• Fixed compat/some, compat/template ([#​2009]), and compat/fill ([#​1952])
  to gate guard handling with isIterateeCall.

• Fixed compat/iteratee to treat a boolean as a property shorthand. ([#​1941])

• Fixed compat/reverse to support array-like objects and arguments. ([#​2008])

• Fixed compat/toArray to convert non-array-like iterables. ([#​1999])

• Fixed compat/toString to render nested nullish values like Lodash. ([#​1992])

• Fixed compat/zipObject to treat null keys and values as empty arrays. ([#​2005])

• Fixed compat/sampleSize to clamp the default size to the collection length. ([#​2003])

• Fixed compat/takeWhile, compat/takeRightWhile, and compat/uniqBy to
  support string inputs. ([#​2004])

• Fixed compat/chunk to return an empty array for an empty collection with an
  Infinity size. ([#​1995])

• Fixed compat/lastIndexOf to read holes in sparse arrays as undefined. ([#​1977])

• Fixed compat/last to return undefined for empty array-like inputs. ([#​1954])

• Fixed compat/pullAll to return the array as-is when values is nullish. ([#​1962])

• Added a browser compatibility test suite. ([#​2012])

• Improved documentation, JSDoc accuracy, tests, and internal refactoring across
  compat and the docs site. ([#​1622], [#​1789], [#​1824], [#​1844], [#​1849],
  [#​1854], [#​1855], [#​1859], [#​1860], [#​1868], [#​1871], [#​1887], [#​1898],

v1.50.0

Compare Source

Released on July 24th, 2026.

• Added the es-toolkit/types entrypoint: a declaration-only module of compile-time
  type utilities TypeScript lacks natively — ValueOf, Simplify, Writable,
  NonEmptyArray, DeepPartial, and DeepReadonly. ([#​1818])
• Added flow to es-toolkit/fp, a reusable data-last composition built on pipe. ([#​1812])

The following bring es-toolkit/compat closer to Lodash. Behavior for the affected
edge cases now matches Lodash, so results may differ if you relied on the previous output.

• Fixed compat/intersectionBy to dedupe a single array (including by the iteratee)
  and to keep results consistent with Lodash. ([#​1935])

• Fixed compat/findIndex and compat/findLastIndex to coerce a NaN fromIndex
  to 0 and to convert fromIndex to an integer. ([#​1828], [#​1834], [#​1938])

• Fixed compat/lastIndexOf to coerce fromIndex like Lodash. ([#​1832])

• Fixed compat/every to treat a falsy, non-nullish doesMatch as a _.property
  shorthand instead of identity. ([#​1940])

• Fixed compat/nth to support string inputs. ([#​1833])

• Fixed compat/inRange to not throw on a lone negative bound. ([#​1835])

• Fixed compat/toArray to convert Sets to arrays like Lodash. ([#​1840])

• Fixed compat/values to treat sparse array holes as undefined. ([#​1894])

• Fixed compat/maxBy and compat/minBy to restore Lodash-compatible comparison. ([#​1893])

• Fixed compat/includes to exclude the length property when matching array-like values. ([#​1886])

• Fixed the case functions to split ordinal numbers like Lodash, and to count string
  size and padding by code points for multi-byte characters. ([#​1836], [#​1852], [#​1853])

• Fixed compat/unset to not treat an own literal dotted key as a deep path. ([#​1808])

• Moved compat/flattenDepth's flattening logic out of flatten. ([#​1847])

• Restored the standalone eq and templateSettings entry points. ([#​1895])

• Fixed deburr to remove all combining diacritical marks, matching Lodash. ([#​1807])

• Fixed partition to accept any predicate return value, like Array.prototype.filter. ([#​1937])

• Fixed has and hasIn to prioritize nullish literal keys over paths. ([#​1810])

• Fixed invokeMap to normalize a string path via toPath for this binding. ([#​1814])

• Fixed isDeepKey to detect deep keys with stricter patterns. ([#​1621])

• Fixed unzipWith to return an empty array instead of throwing on empty input. ([#​1816])

• Improved documentation, JSDoc accuracy, and internal refactoring across compat
  and fp. ([#​1817], [#​1820], [#​1822], [#​1823], [#​1825], [#​1829], [#​1830], [#​1842],
  [#​1845], [#​1851], [#​1858], [#​1867], [#​1879])
