Shouldn't songs.length in the for loop be playList.length since the name of the array is playList?

Shouldn't songs.length in the for loop be playList.length since the name of the array is playList? If not, please help.

var playList = [ [ "", "", ""], [ "", "", ""] ];

for( i = 0; i < songs.length; i += 1 ) { }

If you want to iterate through an array named songs, then it should be songs.length. Here, I guess you want to iterate through the playList array. So, yes, it should be playList.length. By the way, use the var inside the loop conditional. Example:- for( var i = 0; i < songs.length; i += 1 ) { }

What you're saying certainly seems to go with that code snippet, but if these lines are part of a larger project, there could be other things involved. If this is from a course, please provide a link to the course page you are working with.
