Why too much code?

//Why too much code while I can just do this and give the same results:

var PlayList=[
"Love Song", 
"Crazy about you", 
"Lithium", 
"Pretty"
];

document.write("<h1>My Play List</h1>");
document.write("<ol>");
for (var i=0; i<PlayList.length; i++) {
    document.write("<li>"+PlayList[i]+"</li>");
}
document.write("</ol>");

/* Result:
My Play List

1- Love Song
2- Crazy about you
3- Lithium
4- Pretty
*/

Writing a bit more code can make your JS program more dynamic so you don't need to edit more, even though writing less seems best at the start, sometimes writing a little bit more can be very convenient.
