Do we have to always use {} when creating a variable through destructuring?

I have a question regarding nested objects. After creating any object, let’s say we have an object from the example that Codecademy gives us in the lecture “Destructured Assignment”.

const vampire = {
  name: 'Dracula',
  residence: 'Transylvania',
  preferences: {
    day: 'stay inside',
    night: 'satisfy appetite'

why there is no semicolon after closing bracket of nested object “Preferences”?
