Simple numerics

['10',9,2,'1','4'].sort(naturalSort);
// ['1',2,'4',9,'10']

Floats

['10.0401',10.022,10.042,'10.021999'].sort(naturalSort);
// ['10.021999',10.022,'10.0401',10.042]

Float & decimal notation

['10.04f','10.039F','10.038d','10.037D'].sort(naturalSort);
// ['10.037D','10.038d','10.039F','10.04f']

Scientific notation

['1.528535047e5','1.528535047e7','1.528535047e3'].sort(naturalSort);
// ['1.528535047e3','1.528535047e5','1.528535047e7']

IP addresses

['192.168.0.100','192.168.0.1','192.168.1.1'].sort(naturalSort);
// ['192.168.0.1','192.168.0.100','192.168.1.1']

Filenames

['car.mov','01alpha.sgi','001alpha.sgi','my.string_41299.tif'].sort(naturalSort);
// ['001alpha.sgi','01alpha.sgi','car.mov','my.string_41299.tif'

Dates

['10/12/2008','10/11/2008','10/11/2007','10/12/2007'].sort(naturalSort);
// ['10/11/2007', '10/12/2007', '10/11/2008', '10/12/2008']

Money

['$10002.00','$10001.02','$10001.01'].sort(naturalSort);
// ['$10001.01','$10001.02','$10002.00']

Movie Titles

['1 Title - The Big Lebowski','1 Title - Gattaca','1 Title - Last Picture Show'].sort(naturalSort);
// ['1 Title - Gattaca','1 Title - Last Picture Show','1 Title - The Big Lebowski']

By default - case-sensitive sorting

['a', 'B'].sort(naturalSort);
// ['B', 'a']

To enable case-insensitive sorting

naturalSort.insensitive = true;
['a', 'B'].sort(naturalSort);
// ['a', 'B']
