How to merge object in IE 11

rated 0 times [ 69] [ 2] / answers: 1 / hits: 56870 / 7 Years ago, tue, february 7, 2017, 12:00:00

I have the following array of object:

Objs[0] = {Name : "ABC"};

Objs[1] = {Roll : 123}

I'm trying to make it as the following:

Objs {

  Name : "ABC",

  Roll : 123

}

I attempted to make it with the following code:

var Objs = [{

  Name: "ABC"

}, {

  Roll: 123

}];



console.log(

  Object.assign.apply(null, [{}].concat(Objs)) // 1

)

or 



console.log(

  Object.assign({}, ...Objs) // 2

)

The problem is that this is not working in IE 11.

I get the errors:

Error for 1 : Unable to get property 'on' of undefined or null reference

Error for 2 : Object doesn't support property or method 'assign'

Any suggestions on how I should merge the object in IE 11?

IE11 does not support Object.assign.

You could iterate the array and the keys and take the values as new property of the result object.

var objs = [{ Name: ABC }, { Roll: 123 }],

    result =  objs.reduce(function (r, o) {

        Object.keys(o).forEach(function (k) {

            r[k] = o[k];

        });

        return r;

    }, {});



console.log(result);
