Documentation
The following functions are currently implemented:
head(array)
: returns the first element from a given array, or undefined if given an empty arraytail(array)
: returns all elements except the first from a given array, or an empty array if given an empty arrayeqArrays(array1, array2)
: returns true if given arrays are strictly equalwithout(array, unwantedItemsArray)
: returns a subset of given array, removing unwanted elements (those in unwantedItems)middle(array)
: returns the middle-most element(s) of the given arraycountOnly(array, object)
: returns an object containing counts of each key with a value of true listed in the input object that are found in input arraycountLetters(string)
: returns an object where each key represents a letter in the input string and the corresponding value represents the frequency of that letter in the input stringletterPositions(string)
: returns an object where each key represents a letter in the input string and the corresponding value represents the indices that letter can be found in the input stringfindKeyByValue(object, value)
: returns the first key which contains the given value; if value cannot be found in the object, returns undefinedeqObjects(object1, object2)
: returns true if given objects are a perfect match, otherwise returns falsemap(array, callbackFn)
: returns a new array where each element corresponds to the result of callbackFn on an element in the input array with the same indextakeUntil(array, callbackFn)
: returns a subset of the array with elements taken from the beginning until the callback returns a truthy valuefindKey(object, callbackFn)
: returns the first key for which the callbackFn returns a truthy value; if no key is found, returns undefined
