Converting an array in Javascript

Question

How do I convert an array to a form I need cdata to newcdata:

My array is of this format.

var cdata = [
{ name: "Apple", count:1, data: 145 }, 
{ name: "Pear", count:1, data: 185 }, 
{ name: "Apple", count:2, data: 245 }, 
{ name: "Pear", count:2, data: 285 }, 
{ name: "Apple", count:3, data: 345 },
{ name: "Pear", count:3, data: 385 }
];

I need the array to be in this format. How do I convert it?

var newcdata = [
{
    name: "Apple",
    data:[[1,145],[2,245],[3,345]]
},{
    name: "Pear",
    data:[[1,185],[2,285],[3,385]]
}
]
