Types can be viewed of bundles of properties and functions operating on them. Such functions are conventionally called methods. Here’s an example of a simple type:
type Person {
property name String
property age Int
}
This type declaration states that the Person type has two properties. An instance of this type can be created using a new statement:
var p = new Person {
name = "Jane",
age = 18
}
The properties of a type’s instance can be accessed via the dot operator, for example:
return p.name
NB: The pseudocode can be tried out using the Funcy app, which can be downloaded for free from
Apple’s App Store (iOS/macOS),
Google Play (Android) or Amazon Appstore. The code to be executed must be placed in a main {} block. The example above can be tried out by running the following code:
type Person {
property name String
property age Int
}
main {
var p = new Person {
name = "Jane",
age = 18
}
return p.name
}
