How can I add a sub array to an array?

Question

I'm trying to build an array to create a menu system where each index has 2 objects, a name and a subarray of Strings.

I tried something like this:

var menus = [];
menus.push({title:"Aztec", mySubArray:{"String1", "String2","String3"} });

but that doesnt seem to be the right syntax. any ideas?

thanks

You have a syntax error, mySubArray has to be an array []

var menus = [];
menus.push({title:"Aztec", mySubArray:["String1", "String2","String3"] });

mySubArray is not a valid object, because it's missing property names, which makes it an array. You can fix this by either making mySubArray an array:

mySubArray:["String1", "String2","String3"]

or by adding property names to make it an actual object:

mySubArray:{1: "String1", 2: "String2",3: "String3"}

The issue isn't with the fact that it's a "sub array" being pushed, only with the syntax of the actual mySubArray value.
