Documentation
The following functions are currently implemented:
-
function1(head)
: the function returns the first item in the array; -
function2(tail)
: the function returns the "tail" of an array: everything except for the first item (head) of the provided array; -
function3(assertEqual)
: the function compares two values it takes in and print out a message telling us if they match or not; -
function4(eqArrays)
: the function compares two arrays; -
function5(assertArraysEqual)
: the function for asserting that two arrays are equal; -
function6(assertObjectsEqual)
: the function for asserting that two objects are equal; -
function7(countOnly)
: the function takes in a collection of items and returns counts for a specific subset of those items; -
function8(countLetters)
: the function takes in a sentence (as a string) and then return a count of each of the letters in that sentence; -
function9(letterPositions)
: the function returns all the indices (zero-based positions) in the string where each character is found; -
function10(findKeyByValue)
: the function takes in an object and a value. It should scan the object and return the first key which contains the given value; -
function11(eqObjects)
: the function takes in two objects and returns true or false, based on a perfect match; -
function12(findKey)
: the function 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; -
function13(map)
: the function takes in two arguments: an array to map, a callback function. The map function will return a new array based on the results of the callback function; -
function14(takeUntil)
: the function takes in two arguments: an array and a callback function. The function will return a "slice of the array with elements taken from the beginning." It should keep going until the callback/predicate returns a truthy value; -
function15(without)
: the function takes in a source array and a itemsToRemove array. It returns a new array with only those elements from source that are not present in the itemsToRemove array. -
function16(middle)
: the function The middle function returns an array with only the middle element(s) of the provided array;
