Documentation

The following functions are currently implemented:

• assertArraysEqual(actual, expected): compare if actual array is equal to expected array.
• assertEqual(actual, expected): compare if actual value is equal to expected value.
• assertObjectsEqual(actual, expected): compare if actual object is equal to expected object.
• countLetters(string): return a count of each of the letters in the string.
• countOnly(allItems, itemsToCount): counts each specific strings of itemToCount in the collection of strings allItems.
• eqArrays(array1, array2): compare two arrays for a perfect match.
• eqObjects(object1, object2): compare two objects for a perfect match.
• findKey(object, callback: scan the object and return the first key for which the callback returns a truthy value, return undefined if no key is found.
• findKeyByValue(object, value): scan the object and return the first key which contains the given value, return undefined if no key with that given value is found.
• flatten(array): return an one level array with all items of the multi level array.
• head(array): retrieve the first element from the array.
• letterPositions(string): return index(s) of each of the letters in the string.
• map(array, callback): return a new array based on the results of the callback function.
• middle(array): return an array with only the middle element(s) of the array.
• tail(array): retrieve every element except the first element of the array.
