Documentation

The following functions are currently implemented:

• head(array): It takes an array as input and returns the value of the first item (position 0) of the array
• tail(array): It takes an array as input and returns the value of the last item of the array
• middle(array): It takes an array as input and returns the value of the middle position of the array
• eqArrays(arr1, arr2): It compares two arrays then return true or false
• eqObjects(obj1, obj2): It compares two objects then return true or false
• countOnly(obj, objItemToCount): It takes in a collection of items and returns counts for a specific subset of those items
• countLetters(string): It takes in a string of words then return an object with number count for each letter
• findKey(obj, callback): It 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(obj, value): It 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.
• flatten(arrays): It takes in a nested arrays and flatten it into one single array.
• letterPositions(string): It takes in a sentense and return an object with the index of each letter positions
• map(array, callback): It takes in an array and a callback function where it modifies the input array and returns a new array
• takeUntil(array, callback): It takes in an array and a callback function where it sets a condition and return a modified array
• without(array, itemToRemove): It takes in an array and another array of items to be removed from the original array. Returns a new array.
