Reformat string containing date with Javascript

Question

I have the following string which I ultimately need to have in the format of mm/yy

    var expDate = 2016-03;
    var formatExp = expDate.replace(/-/g , \"/\         


        

Answer 1

Do you really need to use RegExp?

Why not creating a simple function that splits the exp Date and returns it the way you want it?

function parseDate(expDate){

     var dateArray = expDate.split('-')
     return dateArray[1] + '/' + dateArray[0].substring(2,4)
}

The split functions creates an array, the element in position 1 is the month, the element in position 2 is the year, on the latter you apply the substring function which extrapolates the last two digits.
