Question

I am trying to do…

a=['a',2,3];
a+=function(){return 'abc'};
console.log(a[3]);

Ergo I want to a.push() in a shorthand way.

Is there any kind of operator that will allow me to do this?

Answer 1

No – and in any case, there’s nothing wrong with:

var a = ['a', 'b', 'c'];
a.push('d');

If you want to push a return value:

a.push((function() { return 'e'; })());
