Anyone know a good way to turn this?:

var obj = [{key1: value1,key2: value2},{key3: value3,key4: value4}];

into:

var obj = [{Key1: value1,Key2: value2},{Key3: value3,Key4: value4}];

Loop through delete and replace:

var obj = [{key1: 1,key2: 1},{key3: 1,key4: 1}];

for(var i = 0; i<obj.length;i++) {



    var a = obj[i];

    for (var key in a) {

        if (a.hasOwnProperty(key)) {

          a[key.charAt(0).toUpperCase() + key.substring(1)] = a[key];

          delete a[key];

          

        }

    }

    obj[i] = a;



}
