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

easiest way to do it where array is of your JSON data :

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

Answer 2

In my case, all other solutions didn't work, but this one did:

obj = {...arr}

my arr is in a form: [name: "the name", email: "the@email.com"]

Answer 3

ES5 Version using .reduce()

const object = array.reduce(function(accumulatingObject, [key, value]) {
  accumulatingObject[key] = value;
  return accumulatingObject;
}, {});
