In the following section of the tutorial. I see array's push method has been used to concatenate string. http://www.html5rocks.com/en/tutorials/file/dndfiles/#toc-selecting-files-input

Example:

x = []
x.push('a','b', 'c')
x.join('') //abc

I found it interesting. But is it a better practice than the usual string concatenation?

It's not. They are just different semantically. – zerkms Sep 15 '15 at 08:24
It's actually a pretty bad tutorial in my opinion, why create an array then concatenate the indexes with join. – EasyBB Sep 15 '15 at 08:26
Actually that tutorial does make sense, you have no way of knowing if the user has selected 10,000 files. – Jamiec Sep 15 '15 at 08:28
