How to access object of array?

I am new to jquery and trying something and got stuck at it, My problem is i have object with array in it i am not able to find the way to access that array from the object 

 //My object is shown in debugging time is as below 

  cache:object 
   0001-:Array[2]
         0:value1,
         1:value2
   _prto_:object

and i want to access the value1 and value2 from the 0001- array from that object is there way to access that array. Any help would be great. I know with $.each i can loop through it and and then again access the array but is there any other way to do it.

You can access it like, and keep in mind that you should use bracket notation in this context, since your keys having a starting character as a number.

cache['0001-'][0] //first element on that array
cache['0001-'][1] //second element

A workaround for your new requirement,

var cache = {'0001-' : [0,1]};
var xKeys = Object.keys(cache);

console.log(xObj[xKeys[0]][0]);
console.log(xObj[xKeys[0]][1]);
