I have an assignment where I'm supposed to make magic out of programming. I'm unable to find any answers online, as I do not know the search term for it (tried method in a method etc...). Appreciate any help given!
Here's what I got: I need to create a class that builds upon itself. e.g.
const pineapple = new Item('pineapple');
pineapple.type = fruit // this is simple
pineapple.is_a.fruit = true // this I do not know
pineapple.is.heavy = true // same thing
I do not even know where to begin. My attempt is similar to this, but I'm getting undefined.
class Thing {
constructor(type) {
this.type = type;
}
is_a(bool) {
this.fruit = this.is_a(bool);
}
}
Assuming that they can be defined in advance, in order to have sub-properties like pineapple.is_a.fruit
, you'll need to define objects on the object's is_a
and is
properties. For instance (see comments):
class Item { // `Item` rather than `Thing`, right?
constructor(type) {
this.type = type;
// Create an `is_a` property that's an object with a `fruit` property
this.is_a = {
fruit: false // Or whatever the initial value should be
};
// Create an `is` property that's an object with a `heavy` property
this.is = {
heavy: false // Or whatever the initial value should be
};
}
}
const pineapple = new Item('pineapple');
pineapple.type = "fruit"; // I added quotes here
console.log("is_a.fruit before:", pineapple.is_a.fruit);
console.log("is.heavy before:", pineapple.is_a.fruit);
pineapple.is_a.fruit = true;
pineapple.is.heavy = true;
console.log("is_a.fruit after: ", pineapple.is_a.fruit);
console.log("is.heavy after: ", pineapple.is_a.fruit);
