Rest Operator for Objects

Now we can use rest on the properties of an Object. It allows us to explicitly extract certain named variables, and assign any uncalled variables into a catchall Object.

const options = {
  enabled: true,
  text: 'Hello',
  color: 'red'
}
const { enabled, ...others } = options
console.log(enabled) // true
console.log(others)  // { text: 'Hello', color: 'red' }
