Documentation
The following functions are currently implemented:
assertArraysEqual(array1, array2)
: compares the two arrays it takes in and prints out a message telling us if they match or not.assertEqual(actual, expected)
: compares the two values it takes in and prints out a message telling us if they match or not.assertObjectsEqual(actual, expected)
: compares the two objects it takes in and prints out a message telling us if they match or not.countLetters(string)
: takes in a sentence (as a string) and then return a count of each of the letters in that sentence.countOnly(allItems, itemsToCount)
: reports back how many instances of each string were found in the allItems array of strings.eqArrays(array1, array2)
: takes in two arrays and returns true or false, based on a perfect match.eqObjects(object1, object2)
: takes in two objects and returns true or false, based on a perfect match.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.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.head(array)
: returns the first item in the array.letterPositions(sentence)
: returns all the indices (zero-based positions) in the string where each character is found.map(array, callback)
: will return a new array based on the results of the callback function.middle(array)
: takes in an array and return the middle-most element(s) of the given array.tail(array)
: returns the "tail" of an array: everything except for the first item (head) of the provided array.takeUntil(array, callback)
: will keep collecting items from a provided array until the callback provided returns a truthy value.without(source, itemsToRemove)
: returns a subset of a given array, removing unwanted elements.
