The following functions are currently implemented:

• head(arr): takes in an array and returns the first element in the array.
• tail(arr): takes in an array and returns everything except the first element of the array.
• eqArrays(arr1,arr2): takes in 2 arrays and returns true if the arrays are equal and false otherwise.
• without(sourceArr, toRemoveArr): takes in a source array and an itemsToRemove arrays and returns only the items from the source array that are not in the itemsToRemove array.
• flatten(arr): takes in an array that contains elements including nested array of elements and returns a flattened version of the array.
• middle(arr): takes in an array and returns middle most element of the array.
• countOnly(itemsArr): takes in a collection of items and returns a specific subset of those items.
• countLetters(sentence): takes in a sentence and returns a count of each of the letters in the sentence.
• letterPositions(string): takes in a string and returns all indices of letter positions in the string.
• findKeyByValue(obj,val): takes in an object and a value and returns the first key that corresponds to that value.
• eqObjects(obj1,obj2): takes in 2 objects and return true if they are equal and false otherwise.
• map(arr,callback): takes in an array and a callback and returns a new array based on the results of the callback on each item in the array.
• takeUntil(arr,callback): takes in an array and callback and returns a slice of the array based on the criteria specified in the callback.
• findKey(obj,callback): takes in an object and callback and returns the first key that meets the criteria specified in callback.
• assertEqual(actual,expected): takes in 2 values and prints out a message telling us if they match or not.
• assertArraysEqual(actualArray,expectedArray): takes in 2 arrays and prints out a message telling us if they match or not.
• assertObjectsEqual(actualObject,expectedObject): takes in 2 objects and prints out a message telling us if they match or not.
