I have an array looking like this:
[Object { id=50, name="My Town"}, Object { id=61, name="My second town"}]
which I need to transform to:
Object { 61=true, 50=true}
How do I do that using underscore.js (or regular js)?
thanks Thomas

You can use just forEach method of native array , in underscore its _.each
var arr = [{ id:50, name:"My Town"},{ id:61, name:"My second town"}];
var obj = {};
arr.forEach(function(val){ obj[val.id] = true; });
console.log(obj)//Object { 61=true, 50=true}

var res = {};
var objs = [ { id: 50 }, { id: 61} ];
objs.forEach(function (d) { res[d.id] = true; });
