How to convert an array of key-value tuples into an object

Question

I have an array:

[ [ \'cardType\', \'iDEBIT\' ],
  [ \'txnAmount\', \'17.64\' ],
  [ \'txnId\', \'20181\' ],
  [ \'txnType\', \'Purchase\' ],
  [ \'txnDate\         


        

Answer 1

When I used the reduce function with acc[i] = cur; it returned a kind of object that I needed to access it like a array using this way obj[i].property. But using this way I have the Object that I wanted and I now can access it like obj.property.

 function convertArraytoObject(arr) {
        var obj = arr.reduce(function (acc, cur, i) {
            acc = cur;
            return acc;
        }, {});
        return obj;
    }
