How do I shift an array of items up by 4 places in Javascript?

I have the following string array:

var array1 = [t0,t1,t2,t3,t4,t5];

I need a function convert array1 to result in:

// Note how t0 moves to the fourth position for example

var array2 = [t3,t4,t5,t0,t1,t2];

Thanks in advance.

array1 = array1.concat(array1.splice(0,3));

run the following in Firebug to verify

var array1 = [t0,t1,t2,t3,t4,t5];

console.log(array1);

array1 = array1.concat(array1.splice(0,3));

console.log(array1);

results in

[t0, t1, t2, t3, t4, t5]

[t3, t4, t5, t0, t1, t2]
