change format in date (Javascript)

Question

I have a very simple query which i am not getting how to correct this format structure.

I have a string as follows

var date = "11/21/2016'

I need to change it to this format

var date = '20161122'

Any idea how to achieve this

Answer 1

If you do not want to use a library:

var parts = date.split("/");
var finalDate = parts[2] + parts[0] + parts[1];

The finalDate is the answer.

Answer 2

I'd like to suggest moment.js:

moment('11/21/2016', 'MM/DD/YYYY').format('YYYYMMDD')
