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

You can use spread syntax as follows..

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

alerts = {...alerts, 3: {app: 'hey there', message: 'another message'} }
