Bumps es-toolkit from 1.50.0 to 1.52.0.

Release notes

Sourced from es-toolkit's releases.

v1.52.0

Released on August 28th, 2026.

• Added the es-toolkit/iterator entrypoint, a lazy iterator module with chunk, count, dropWhile, head, iterate, partition, range, scan, takeWhile, uniqBy, and zip ([#1815]), plus cartesianProduct ([#2031]). The same functions are also available from es-toolkit/fp/iterator.

• Added defer and deferAsync to es-toolkit/util. ([#2032])

• Added flowAsync to es-toolkit/fp, a promise-aware left-to-right composition. ([#2033])

• Added the EmptyObject, IsEqual, JSONValue, Primitive, SetOptional, SetRequired, and UnknownRecord types. ([#2044])

• Fixed merge to infer the deep merged return type, and exported the Merge type. ([#1959])

• Fixed omitBy and pickBy to type numeric callback keys as strings, and exported the ObjectKeys type. ([#2037])

• Fixed attempt and attemptAsync to default their error type parameter to unknown. ([#2052])

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/debounce to skip the maxWait invocation when both leading and trailing are false. ([#1678])

• Fixed compat/toString to convert objects with a custom valueOf. ([#2034])

• Fixed compat/mergeWith to assign null values in array sources. ([#1929])

• Fixed compat/has and compat/hasIn to normalize the -0 path key. ([#2035])

• Fixed compat/differenceWith and compat/without to normalize -0 to 0. ([#2049])

• Fixed compat/findLastIndex to convert fromIndex to an integer. ([#2047])

• Fixed compat/xorWith to match Lodash when no comparator is given. ([#2057])

• Covered the new iterator entrypoints in the dist and browser compatibility checks. ([#2030])

• Made the agent skills portable when installed on their own. ([#2054])

• Fixed documentation typos and the Deno install commands. ([#2062])

v1.51.0

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])
