Object Helpers

Utility functions for working with object operations.

Functions

Function	Description
clone	Creates a shallow copy of a value — one level deep, unlike cloneDeep.
cloneDeep	Creates a deep copy of an object or array.
compact	Removes all entries with falsy values (false, null, undefined, 0, "", NaN) from an object.
diff	Structural object diff.
equalsDeep	Recursive structural object equality.
equalsShallow	One-level (shallow) object equality.
flatten	Flattens a nested object into a single-level object whose keys are the dot-notation path to each leaf value.
get	Gets a value from an object using a dot/bracket-notated path or explicit key array.
groupBy	Groups an array of items by a key derived from each item.
has	native JS Object.hasOwn(obj, key) (ES2022)
invert	Returns a new object with keys and values swapped.
isEmpty	Checks if a plain object has no own enumerable string-keyed properties.
isNonEmpty	Checks if a plain object has at least one own enumerable string-keyed property.
keys / values	native JS Object.keys() / Object.values() (ES2017)
map	Transforms the values and/or keys of a plain object in a single pass.
merge (shallow)	native JS { ...a, ...b } or Object.assign({}, a, b) (ES2015)
mergeDeep	Merges two or more objects deeply, returning a new object without mutating any input.
omit	Creates a new object without the specified keys.
omitBy	Creates a new object without the own enumerable entries for which predicate returns true.
parsePropertyPath	Parses a dot/bracket-notation property path into an array of string/number key segments — the same notation accepted …
pick	Creates a new object with only the specified keys.
pickBy	Creates a new object with only the own enumerable entries for which predicate returns true.
removeUndefinedNull	Remove null and undefined values from an object.
safeJsonParse	Parses a JSON string, returning null (or a fallback) on any parse failure.
set	Sets a value in an object at the given path, creating intermediate objects as needed.
toPairs / fromPairs	native JS Object.entries() / Object.fromEntries() (ES2019)
unflatten	Rebuilds a nested object from a single-level object whose keys are dot-notation paths.
unset	Removes the value at a dot/bracket-notation path or explicit key array, mutating the object in place.
update	Updates the value at a path by applying a function to its current value, creating intermediate objects as needed.
