I have a string of a date in javascript in format #1. I need to convert it to format #2.
The problem starts when one format is \"dd/mm/yy\" and the other is \"mm/dd/
You should look into momentjs, which is a javascript date/time library. With that, you can easily convert between dates of different format. In your case, it would be:
string newDate = moment(currentDate, currentFormatString).format(newFormatString)
For example, moment("21/10/14", "DD/MM/YY").format("MM/DD/YY") would return "10/21/14"
