Documentation

The following functions are currently implemented:

• head (array): takes in an array and returns the first item of that array.

• tail (array): takes in an array and removes the first element and returns the remainder of that array.

• middle (array): takes in an array and returns the single middle element if odd, and middle two elements if even.

• countLetters (str): takes in a string and returns the total number of letters in the string.

• countOnly (allItems, itemsToCount): takes in an array of items, and the item that needs to be tracked, then counts the times that item has been repeated in an array.

• findKey (object, callback): takes in an object and a callback function, it then scans the object and return the first key for which the callback returns a truthy value.

• findKeyByValue (list, value): takes in an object and a value, it then scans the object and return the first key which contains the given value.

• flatten (multipleArrays): takes in an array of nested arrays and returns all the element inside one single array.

• letterPositions (str): takes in a string and returns the index of each letter within that string.

• map (array, callback): takes in an array to map, and a callback function, returns a new array based on the results of a callback function.

• takeUntil (array, callback): takes in an array and a callback function. Keeps collecting items from the array until the callback provided returns a truthy value and returns a slice of the array with elements taken from the beginning.

• without (source, itemsToRemove):takes in an array of all items, and a second array cintaining the items to remove. Then returns a subset of a given array, removing unwanted elements.
