Problems to solve using Underscore's functions

Find out if any of the numbers in the array are divisible by three.  If there is at least one, return true, if not, return false.

var testArray2 = [4,8,12,16,20,24,28,32,40,44,48,52,56,60,64,68,72,76,80,84,88,92,96,100,104,108,112,116,120,124,128,132,136,140,144,148,152,3,156,160,164,168,172,176,180,184,188,192,196,200,204];


var testArray1 = [4,8,12,16,20,24,28,32,40,44,48,52,56,60,64,68,72,76,80,84,88,92,96,100,104,108,112,116,120,124,128,132,136,140,144,148,152,3,156,160,164,168,172,176,180,184,188,192,196,200,204];


_.some can do this very easily.  

Both the above arrays will return true.  However, this one should return false:


var testArray3 = [2,1,4,5,7,8,10,11,13,14,16,17,19,20,22,23,25,26,28];
