The code above actually overwrites everything in
account
andnewAccount
withname: 'Test User'
etc., even ifnewAccount.name
has a value. Not sure if that's what you wanted.To merge the objects with precedence to supplied
newAccount
properties, use:const account = Object.assign({name: 'Test User', entryYear: '2001', major: 'Mechanical Engineering'}, newAccount)
(if you keep the defaults as an object literal – in that case, the literal is mutated into the merged object each time)or
const account = Object.assign({}, AccountDefaults, newAccount)
(if you move the defaults to a global).If you're using redux, you've probably got Babel / webpack set up with the object rest spread operator. In that case, you can also write
const account = {...AccountDefaults, ...newAccount}
