Using an array inside a map = { [ ] } in Javascript -

it doesn't seem possible declare map that, there way it?

i want kind of functionality:

var map = {[]}; // doesn't compile  map["first"] = [1,2,3]; map["second"][0] = 4; map["second"][1] = 5;  console.log(map["first"][1]);   // want print 2 here console.log(map["second"][1]);  // should print 5 

is there way map similar this?

your code work perfectly.

edit: add new array object, need add new array object:

map.second = []; 

if you're not sure whether exists yet, can check:

if (!map[somekey]) map[somekey] = [];
