Can I set the value of a property dynamically?

I have the following:

    var data.roles = "Admin:Xxxx:Data";

    for (role in data.roles.split(':')) {
        if (role == 'Admin') { user.data.role.isAdmin = true }
        if (role == 'Data')  { user.data.role.isData = true }
        if (role == 'Xxxx')  { user.data.role.isXxxx = true }
        if (role == 'Test')  { user.data.role.isTest = true }
    }

Is there a way that i could make this work without the if checks. What I would like is to have a solution that would work for any role that is present in data.roles.

Since split returns an Array, you could use forEach:

var data = {roles: "Admin:Xxxx:Data"};
var user = {data: {role:{}}};

data.roles.split(':').forEach(function(v) {
  user.data.role['is' + v] = true; 
})

console.log(user.data.role.isXxxx); // true

There is a polyfill at MDN for browsers without forEach.
