JavaScript (Node.js v6.7.0)

var s = 'abc';
s.split();   // [ 'abc' ]
s.split(''); // [ 'a', 'b', 'c' ]

'hello world'.split();     // [ 'hello world' ]
'hello world'.split(' ');  // [ 'hello', 'world' ]

''.split();     // [ '' ]
''.split(' ');  // [ '' ]

Python 2

s = 'abc'
s.split()    # ['abc']
s.split('')  # error! empty separator
list(s)      # ['a', 'b', 'c']

'hello world'.split()     # ['hello', 'world']
'hello world'.split(' ')  # ['hello', 'world']

''.split()     # []
''.split(' ')  # ['']
