Will you explain more, this is basically a representation of empty array.

  var a = [];

"a" is a bucket being set aside to put things in later, perhaps when going through a loop.

Hi Patti!

the brackets [] represent an empty array. An array is basically a list of values in a single variable that you want to do something with so you don't have to create multiple variables of very similar objects, strings, integers, etc. There are many, many reasons to use an array but if you are confused on Dave's usage of arrays I highly recommend reviewing the video and taking notes.
