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

use the following way to convert the array to an object easily.

var obj = {};
array.forEach(function(e){
   obj[e[0]] = e[1]
})

This will use the first element as the key and the second element as the value for each element.
