Documentation
The following functions are currently implemented:
assertArraysEqual(actual, expected)
: This function takes in two arrays and console.log an appropriate message to the console.assertEqual(actual, expected)
:This function compares the two values it takes in, and prints out a message telling us if they match or not.assertObjectsEqual(actual, expected)
: This function takes in two objects and console.log an appropriate message to the console.countLetters(str)
: This function takes in a sentence (as a string) and then return a count of each of the letters in that sentence.countOnly(allItems, itemsToCount)
: This function will be given an array and an object. It will return an object containing counts of everything that the input object listed.eqArrays(arr1, arr2)
: This function takes in two arrays and returns true or false, based on a perfect match.eqObjects(obj1, obj2)
: This function take in two objects and returns true or false, based on a perfect match.findKey(object, callback)
: This function takes in an object and a callback, It scans the object and return the first key for which the callback returns a truthy value.findKeyByValue(key, value)
: This function takes in an object and a value. It should scan the object and return the first key which contains the given value.head(arr)
: This function returns the first item in the array.letterPositions(sentence)
: This function will return all the indices (zero-based positions) in the string where each character is found.map(array, callback)
: This function takes in an array and a callback function, and returns a new array based on the results of the callback function.middle(arr)
: This function will take in an array and return the middle-most element(s) of the given array.tail(arr)
: This function returns the "tail" of an array: everything except for the first item (head) of the provided array.takeUntil(array, callback)
: This function will keep collecting items from a provided array until the callback provided returns a truthy value.without(source, itemsToRemove)
