Spread operator

In order to update an existing object, you can use the ... spread operator. This will create a new version of the object, which you can then modify fields on. For example:

type alias Person = {
    age: number,
    name: string
}

person: Person
person = { age: 27, name: "Noah" }

olderPerson: Person
olderPerson = { ...person, age: 79 } -- equal to { age: 79, name: "Noah" }
