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
