Question

I have an array of objects like so

obj = [
    {
      id: 3,
      data: foo
    },
    {
      id: 7,
      data: bar
    }
]

but I need to get it to

 obj = {
    3: {
        id: 3,
        data: foo
    },
    7: {
        data: bar
    }
 }

having the id in the sub object is not needed but might be handy. What would be the best way to achieve this? I am not sure if there is a simple way to extract a property as an index?

Thanks for any help!

Answer 1

obj2 = {};
obj.forEach(function(x){
    obj2[x.id] = x;
});
