type.Integer

Provides a type that can be used with can-observable-object and other APIs that accept a TypeObject. Resolves to a strict Integer. JavaScript does not have a native Integer type, so this provides one.

An integer is a whole, non-fractional, number.

import { ObservableObject, type } from "can";

class Fruit extends ObservableObject {
  static props = {
    apples: type.convert(type.Integer),
    oranges: type.check(type.Integer)
  };
}

let fruit = new Fruit();
fruit.apples = 6.3;
fruit.oranges = 7;

console.log("Apples", fruit.apples, "Oranges", fruit.oranges);

fruit.oranges = 7.1; // throws!
