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

Do you have the ability to change the outer-most structure to an array? So it would look like this

var alerts = [{"app":"helloworld","message":null},{"app":"helloagain","message":"another message"}];

So when you needed to add one, you can just push it onto the array

alerts.push( {"app":"goodbyeworld","message":"cya"} );

Then you have a built-in zero-based index for how the errors are enumerated.
