Javascript basic¶
Overview¶
With ECMAScript since 2015 you can use Spread Syntax ( …three dots):
let people = { id: 4 ,firstName: 'John'};
people = { ...people, secondName: 'Fogerty'};
It's allow you to add sub objects:
people = { ...people, city: { state: 'California' }};
the result would be:
{
"id": 4,
"firstName": "John",
"secondName": "Forget",
"city": {
"state": "California"
}
}
