const vampire = {
  name: 'Dracula',
  residence: 'Transylvania',
  preferences: {
    day: 'stay inside',
    night: 'satisfy appetite'
  }
};
const residence = vampire.residence; 
console.log(residence); // Prints 'Transylvania'

const { residence } = vampire; 
console.log(residence); // Prints 'Transylvania'

//Look back at the vampire object’s properties in the first code example. Then, in the example above, we declare a new variable residence that extracts the value of the residence property of vampire. When we log the value of residence to the console, 'Transylvania' is printed.
//We can even use destructured assignment to grab nested properties of an object:

const { day } = vampire.preferences; 
console.log(day); // Prints 'stay inside'



const robot = {
  model: '1E78V2',
  energyLevel: 100,
  functionality: {
    beep() {
      console.log('Beep Boop');
    },
    fireLaser() {
      console.log('Pew Pew');
    },
  }
};

const { functionality } = robot;

functionality.beep();

Required Parameters for Functions in JavaScript

 const isRequired = () => { throw new Error('param is required'); };

const hello = (name = isRequired()) => { console.log(`hello ${name}`) };

// These will throw errors
hello();
hello(undefined);

// These will not
hello(null);
hello('David');
The idea here is that it uses default parameters, like how the b parameter here has a default if you don’t send it anything:
function multiply(a, b = 1) {
  return a * b;
}
