README

        
# getFirstAlphabetical(items): any

Creates a copy of `items` re-arranged in alphabetical order and returns the  

first item in sorted result.  

Does not modify `items`.

# getLastAlphabetical(items): any

Creates a copy of `items` re-arranged in alphabetical order and returns the  

last item in sorted result.  

Does not modify `items`.

For both functions:  if not every item in `items` is type 'string',  

the function will attempt to coerce the item into a string before  

doing the comparisons.  None of the items are modified.

Since `items` can technically include any data type, it's possible  

any data type could end up being the first or last item in the  

sorted result.

## Examples

```

let items = ['c', 'a', 'e', '', 'g', 'j', 'z', 'o', 'r', 'x', '!'];

getFirstAlphabetical(items);

    // -->  ''

    

getLastAlphabetical(items);

    // -->  'z'

  

    

items = ['aa', 'a', 'A', 'AA'];

getFirstAlphabetical(items);

    // -->  'A'

    

getLastAlphabetical(items);

    // -->  'aa'

items = ['John Adams', 'Ben Franklin', 'William Shakespeare', 'JJ Abrams', 

          'Bob Newhart', 'Walter Cronkite'];

getFirstAlphabetical(items);

    // -->  'Ben Franklin'

getLastAlphabetical(items);

    // --> 'William Shakespeare'

items = ['today', null, false, true];

getFirstAlphabetical(items);

    // -->  false

    

getLastAlphabetical(items);

    // --> true

    

    

items = [0, false, [], {}, ''];

getFirstAlphabetical(items);

    // -->  []

    

getLastAlphabetical(items);

    // --> false

```

## Installation
