Question

I have a structure like the following:

skillet.person = {
  name: {
    first: \'\',
    last: \'\'
  }, 
  age: {
    current: \'\' 
  },
  birthday: {
    day:         


        

Answer 1

skillet.person.name.first = "blah"
skillet.person.name.last = "ha"

or

skillet.person.name = {first : "blah", last : "ha"}
