javascript - Cross product in underscore.js? -

-

is there function built-in underscore give "cross product" of 2 arrays?

i have implemented cross-product this, nice if there built-in function --

domain = []; _.each(x, function(x1) {     _.each(y, function(y1) {         domain.push([x1,y1]);     }); });

you can use _.mixin extend underscore own function.
