Spread operator within ternary operator

[lewispham]

I think it would be nice to be able to use spread operator like this:

var x = [1,2];
var y = [];
y.push(x instanceof Array ? ...x : x);

See leobalters version, if your usecase needs push you can use:

var x = [1,2];
var y = [];
y.push(...Array.isArray(x) ? x : [ x ]);

@leobalter Very nice suggestion if I don't mind creating a new array.

@topaxi It looks like a workaround rather than an official method for the case. Also, I personally think it's a bit less readable.
