ES6 object destructuring mandatory parameters

Last updated: 
Published: 

Couple of days ago I came across this cool trick to validate required fields using ES6 default function parameters.

function throwRequired(name) {
  throw new Error(`'${name}' is required`)
}

function name({
  id = null,
  name = 'user',
  password = throwRequired('password'),
}) {
  console.log('All is good, password is: ' + password)
}

I haven't actually used it so far, just tested in Chrome DevTools.

Check out the StackOverflow question all this originates from.
