Documentation

The following functions are currently implemented:

• head(array): Returns the first element of the array (in string format).
• middle(array): Returns the middle element of the array, middle 2 elements if length is even.
• tail(array): Returns all elements after the first element of an array.
• countLetters(string): Returns an object with a count of instances for each letter eg {a: 5, b:2} with non occuring letters being undefined.
• countOnly(array, object): Counts only the items in an array that are defined as true in the input object eg {Zack: true, banana: false, Kelly: true} will count instances of Zack and Kelly in the array but not instances of banana or any other item.
• findKey(object, callback): Returns the first key that returns true when its value is passed into the callback function.
• findKeyByValue(object, valueToFind): Returns the first key who's value matches the input value.
• flatten(array): Returns an array with all elements un-nested eg [1, [2, 3] becomes 1, 2, 3.
• letterPositions(string): Returns an object with an array for each occuring letter with the indexed positions of that letter.
• map(array, callback): Creates an array that contains the result of the callback function's output for each value in the original array.
• taleUntil(array, callback): Returns an array of items added 1 at a time from original array until a value returns true when passed to callback function.
• without(array, itemsToRemove): Returns an array of all the values in input array that do not match values in itemsToRemove.
