13,135 PointsHi, I have got a couple of questions about this video.
function print(message) { document.write(message); }
I do not understand the sense of this chunk of code and why it is necessary. Then
function printList( list ) {
var listHTML = '<ol>';
for ( var i = 0; i < list.length ; i += 1 ) {
listHTML += '<li>' + list[i] + '</li>'
}
listHTML += '</ol>';
print(listHTML);
}
In this function, we are using list as a parameter so the loop is running until it reach the list.length value, but when have we define it?
Thank you in advance to everyone..

The first one seemed a bit odd to me also.
So print is basically just a shorthand for document.write. It just makes the code a bit more compact.
And as you suspected, printList converts a play list into an HTML ordered list and a set of list items to be displayed on the page.

13,135 PointsOooook, I have probably solved the second one list is the parameter that is substituted with the playList value when we are using the function at the end of the code.
