Documentation

The following functions are currently implemented:

• assertArraysEqual(arr1, arr2): Compares actual and expected arrays and returns passed or failed.
• assertEqual(actual, expected): Compares expected and actual values.
• assertObjectsEqual(actual, expected): Compares actual and expected objects and returns passed or failed.
• countLetters(sentance): Counts the number of character occurances in a string.
• countOnly(allItems, itemsToCount): Counts the number of times a string occurs in an array.
• eqArrays(array1, array2): Compares two arrays and returns a boolean if the arrays are the same/different.
• eqObjects(object1, object2): Compares two objects and returns a boolean if the object are the same/different.
• findKey(object, callback): Takes an object and a callback. Scans the object and returns the first key for which the callback returns a truthy value.
• findKeyByValue(object, value): Takes in an object and a value. It scans the object and returns the first key with the given value.
• head(array): Returns the first element of an array.
• letterPositions(sentance): Returns the index in which a letter occurs in a string within an array.
• map(array, callback): Returns the first letter of each element in an array of strings.
• middle(array): Returns the middle value (of odd) or values (if even) in an array longer than two elements.
• tail(actual): Removes the first element in an array and returns the remaining elements in a new array.
• takeUntil(array, callback): Takes an array and a callback function. Returns a new array of items occuring until the point specified by the callback functions.
• without(source, itemsToRemove): Takes an array and items to remove. Returns a new array without the removed items.
