Appending to an object

Question

I have an object that holds alerts and some information about them:

var alerts = { 
    1: { app: \'helloworld\', message: \'message\' },
    2: { app: \'hel         


        

Answer 1

Now with ES6 we have a very powerful spread operator (...Object) which can make this job very easy. It can be done as follows:

let alerts = { 
   1: { app: 'helloworld', message: 'message' },
   2: { app: 'helloagain', message: 'another message' }
} 

//now suppose you want to add another key called alertNo. with value 2 in the alerts object. 

alerts = {
   ...alerts,
   alertNo: 2
 }

Thats it. It will add the key you want. Hope this helps!!
