Objects: Passing objects as function arguments or returning objects from a function

It’s common to pass objects as parameters to functions, and to return objects from a function.

Like this:

const printNameAndAge = ({ name, age }) => {
  console.log(name, age)
}

const person = {
  name: 'Flavio',
  age: 38
}

printNameAndAge(person)

//or

printNameAndAge({ name: 'Roger', age: 9 })

We use objects as a “trick” to return multiple values from a function:

function test() {
  const name = 'Flavio'
  const age = 38

  return { name, age }
}

Then you can call the function and save the object to a variable, or use object destructuring like this:

const { name, age } = test()
