lodash-recreated is a vanilla JavaScript Re-Creation of the popular library Lodash with Array, Object, Collection, Util and Lang utility methods, along with unit-tests written for each of the implemented methods.
-
- chunk(array, [size=1])
Creates an array of elements split into groups the length of size.
If array can't be split evenly, the final chunk will be the remaining elements.
https://lodash.com/docs/4.17.15#chunk- compact(array)
Creates an array with all falsey values removed.
The valuesfalse, null, 0, "", undefined, and NaNare falsey.
https://lodash.com/docs/4.17.15#compact- concat(array, [values])
Creates a new array concatenating array with any additional arrays and/or values.
https://lodash.com/docs/4.17.15#concat- difference(array, [values])
creates an array of array values not included in the other given arrays using SameValueZero for equality comparisons.
https://lodash.com/docs/4.17.15#difference- differenceBy(array, [values], [iteratee=_.identity])
This method is like difference except that it accepts iteratee which is invoked for each element of array and values to generate the criterion by which they're compared. The order and references of result values are determined by the first array.
https://lodash.com/docs/4.17.15#differenceBy- differenceWith(array, [values], [comparator])
This method is like _.difference except that it accepts comparator which is invoked to compare elements of array to values. The order and references of result values are determined by the first array. The comparator is invoked with two arguments: (arrVal, othVal).
https://lodash.com/docs/4.17.15#differenceWith- drop(array, n = 1)
creates a slice of an array with n elements dropped from the beginning.
https://lodash.com/docs/4.17.15#drop- dropWhile(array, [predicate=_.identity])
Creates a slice of array excluding elements dropped from the beginning, Elements are dropped until the predicate returns falsey.
https://lodash.com/docs/4.17.15#dropWhile- dropRight(array, [n = 1])
Creates a slice of array with n elements dropped from the end.
https://lodash.com/docs/4.17.15#dropRight- dropRightWhile(array, predicate)
Creates a slice of array excluding elements dropped from the end. Elements are dropped until predicate returns falsey.
https://lodash.com/docs/4.17.15#dropRightWhile- flatten(array)
Flattens array a single level deep.
https://lodash.com/docs/4.17.15#flatten- flattenDeep(array)
Recursively flattens array.
https://lodash.com/docs/4.17.15#flattenDeep- flattenDepth(array, [depth = 1])
Recursively flatten array up to depth times.
_.flattenDepth(array, [depth=1])- fromPairs(pairs)
this method returns an object composed from key-value pairs(arrays).
https://lodash.com/docs/4.17.15#fromPairs- intersection([arrays])
Write a function that creates an array of values found within all given arrays.
The first array will serve as the base from which the remaining arrays will be checked to see if they have the matching values.
https://lodash.com/docs/4.17.15#intersection- nth(array, [n=0])
Gets the element at index n of array.
If n is negative, the nth element from the end is returned.
_.nth(array, [n=0])- pull(array, [values])
Removes all given values from array using SameValueZero for equality comparisons.
https://lodash.com/docs/4.17.15#pull- tail(array)
Gets all but the first element of array.
https://lodash.com/docs/4.17.15#tail- uniq(array)
Creates a duplicate-free version of an array, using SameValueZero for equality comparisons,
in which only the first occurrence of each element is kept. The order of result values
is determined by the order they occur in the array. https://lodash.com/docs/4.17.15#uniq -
- get(object, path, [defaultValue])
Gets the value at path of object.
If the resolved value is undefined, the defaultValue is returned in its place.
https://lodash.com/docs/4.17.15#get -
- find (collection, predicate, startIndex)
Iterates over elements of collection, returning the first element predicate returns truthy for.
The predicate is invoked with three arguments: (value, index|key, collection).
https://lodash.com/docs/4.17.15#find- groupBy(collection, [iteratee=_.identity])
Creates an object composed of keys generated from the results of running each element of collection thru iteratee.
The order of grouped values is determined by the order they occur in collection.
https://lodash.com/docs/4.17.15#groupBy- countBy(collection, [iteratee=_.identity])
Creates an object composed of keys generated from the results of running each element of collection thru iteratee.
The corresponding value of each key is the number of times the key was returned by iteratee.
https://lodash.com/docs/4.17.15#countBy- every(collection, [predicate=_.identity])
Checks if predicate returns truthy for all elements of collection.
Iteration is stopped once predicate returns falsey
https://lodash.com/docs/4.17.15#every- invokeMap(collection, path, [args])
Invokes the method at path of each element in collection, returning an array of
the results of each invoked method. Any additional arguments are provided to each invoked method.
. If path is a function, it's invoked for, and this bound to, each element in collection.
https://lodash.com/docs/4.17.15#invokeMap- keyBy(collection, iteratee)
Creates an object composed of keys generated from the results of
running each element of collection thru iteratee. The corresponding value of each key is
the last element responsible for generating the key.
The iteratee is invoked with one argument: (value).
https://lodash.com/docs/4.17.15#keyBy -
- clamp(number, [lower], upper)
Clamps number within the inclusive lower and upper bounds.
https://lodash.com/docs/4.17.15#clamp- random(lower = 0, upper = 1, floating = false)
Produces a random number between the inclusive lower and upper bounds.
If only one argument is provided a number between 0 and the given number is returned.
If floating is true, or either lower or upper are floats, a floating-point number is returned.
https://lodash.com/docs/4.17.15#random- inRange(number, [start=0], end)
Checks if n is between start and up to, but not including, end.
If end is not specified, it's set to start with start then set to 0.
If start is greater than end the params are swapped to support negative ranges.
https://lodash.com/docs/4.17.15#inRange -
- isArguments(value)
Checks if value is likely an
Argumentsobject.
https://lodash.com/docs/4.17.15#isArguments- isArray(value)
Checks if value is classified as an
Arrayobject.
https://lodash.com/docs/4.17.15#isArray- isArrayBuffer(value)
Checks if value is classified as an
ArrayBufferobject.
https://lodash.com/docs/4.17.15#isArrayBuffer- isArrayLike(value)
Checks if value is array-like. A value is considered array-like if
it's not a function and has a value.length that's an integer
greater than or equal to 0 and less than or equal to Number.MAX_SAFE_INTEGER.
https://lodash.com/docs/4.17.15#isArrayLike- isArrayLikeObject(value)
This method is like
isArrayLikeexcept that it also checks if value is an object.
https://lodash.com/docs/4.17.15#isArrayLikeObject- isBoolean(value)
Checks if value is classified as a boolean primitive or object.
https://lodash.com/docs/4.17.15#isBoolean- isBuffer(value)
Checks if value is a buffer.
https://lodash.com/docs/4.17.15#isBuffer- isDate(value)
Checks if value is classified as a Date object.
https://lodash.com/docs/4.17.15#isDate- isEmpty(value)
Checks if value is an empty object, collection, map, or set.
Objects are considered empty if they have no own enumerable string keyed properties.
Array-like values such as arguments objects, arrays, buffers, strings
are considered empty if they have a length of 0.
Similarly, maps and sets are considered empty if they have a size of 0.
https://lodash.com/docs/4.17.15#isEmpty
