Documentation

The following functions are currently implemented:

• assertArrayEquals(actual, expected): asserts if two arrays are equals
• assertEqual(actual, expected): asserts if two values are equals
• assertObjectsEqual(actual, expected): asserts if two objects are equals
• countLetters(letters): returns the count of each letter within the string
• countOnly(allItems, itemsToCount): counts and returns occurrence of object within the array.
• eqArrays(first, second): compares for equality between two arrays. Recursive for arrays within arrays.
• eqObjects(first, second): compares for equality between two objects. Recursive for objects within objects.
• findKey(obj, cb): scans the object and return the first key for which the callback returns a truthy
• findKeyByValue(object, value): takes an obeject and returns the key of the object value.
• flatten(array): flattens an array of arrays into a single-level array
• head(item): returns the 1st element of an array
• letterPositions(sentence): returns all the indices/position of each character in the string
• map(array, callback): returns a new array with the applied callback on the original array
• middle(array): returns the middle element of an array
• tail(items): returns the entire array minus the first element.
• takeUntil(array, callback): returns an array with elements upto the callback provided
