Documentation
The following functions are currently implemented:
-
function1(head): A function that will retrieve the first element from an array. -
function2(tail): A function that retrieve the tail of an array, is meant to be every element except the head (first element) of the array. -
function3(middle): A function which will take in an array and return the middle-most element(s) of the given array. -
function4(map): A function that will receive an array and a callback function to return a new array with callback function does a process on each element of the initial array. -
function5(letterPositions): A function which will return all the indices (zero-based positions) in the string where each character is found. -
function6(findKey): A function which will take in an object and a callback, and will return the first key for which the callback returns a truthy value. If no key is found, then it should return undefined. -
function7(findKeyByValue): A function which takes in an object and a value, and will return the first key which contains the given value. If no key with that given value is found, then it should return undefined. -
function8(eqArrays): A function that will take in two arrays and returns true or false, based on a perfect match. -
function9(countLetters): A function which should take in a sentence (as a string) and then return a count of each of the letters in that sentence. -
function10(countOnly): A function which will be given an array and an object. It will return an object containing counts of everything that the input object listed. -
function11(eqObjects): A function which will take in two objects and returns true or false, based on a perfect match. -
function12(takeUntil): A function which will keep collecting items from a provided array until the callback provided returns a truthy value. -
function13(withOut): A function that will return a subset of a given array, removing unwanted elements. -
function14(flatten): A function, given an array with other arrays inside, it can flatten it into a single-level array.
