Documentation

The following functions are currently implemented:

• _.head(array) : returns firt element of an array
• _.tail(array) : pushes all, but first element of the array to the new array
• _.middle(array) : returns the middle element of the array, in case if array length is even number, returns 2 middle elements
• _.countLetters(string) : returns the # of occurances of each letter in the string in the form of object
• _.countOnly(allItems, itemsToCount) : returns the number of occurances for certain array (allItems) element, given the object key value of true/false
• _.eqArrays(array1,array2) : returns true/false when comapring two arrays. If equal return true, and if not equal return false.
• _.eqObjects(obj1, obj2) : returns true/false when comapring two objects and its values and keys. If equal then returns true.
• _.findKey(object, callback) : returns the specified key when callback function condition is satisfied
• _.findKeyByValue(object, value) : returns the key of the given value within the object
• _.flatten(array) : returns flattened input array
• _.letterPositions(string) : returns the index of every letter in the string in the form of the object
• _.map(array, callback) : returns first character of each string in the array
• _.takeUntil(array, callback) : iterrates over the array and pushes values to new array until a specified callback function condition
• _.without(source, remove) : removes the specified value from the array
• _.assertArraysEqual(actual, expected) : asserts if either array1 = array2 and returns either PASS or FAIL
• _.assertEqual(actual, expected) : asserts if either actual and expected values are equal
• _.assertObjectsEqual() : asserts if either actual object snd expected object are equal
