Documentation
The following functions are currently implemented:
head(array)
: simpler array-handling functions to retrieve the first element from the array.tail(array)
: simpler array-handling functions to retrieve every element except the head (first element) of the array.without(array)
: return a subset of a given array, removing unwanted elements.flatten(array)
: take in an array containing elements including nested arrays of elements, and return a "flattened" version of the array.middle(array)
: take in an array and return the middle-most element(s) of the given array.countOnly(array, object)
: countOnly will be given an array and an object. It will return an object containing counts of everything that the input object listed.countLetters(string)
: take in a sentence (as a string) and then return a count of each of the letters in that sentence.letterPositions(string)
: return all the indices (zero-based positions) in the string where each character is found.findKeyByValue(object, value)
: takes in an object and a value. It should scan the object and return the first key which contains the given value. If no key with that given value is found, then it should return undefined.map(array, callback)
: takes in an array and a callback function. It would return a new array which contains the result of all elements processed by the callback function.takeUntil(array, callback)
: return a "slice of the array with elements taken from the beginning." It should keep going until the callback/predicate returns a truthy value.findKey(object, callback)
: takes in an object and a callback. It should scan the object and return the first key for which the callback returns a truthy value. If no key is found, then it should return undefined.
