I have this and I can't use the method in the class because of the error shown below.
class Product {
a:number
b:number
get total() {
return this.a * this.b;
}
}
var product: Product={
a:2,
b:3
}
The error:
Type '{ a: number; b: number; }' is not assignable to type 'Product'. Property 'total' is missing in type '{ a: number; b: number; }'.
You should probably use a constructor instead:
class Product {
constructor(private a: number, private b: number) {}
get total(): number {
return this.a * this.b;
}
}
let product: Product = new Product(2, 3);
Do not confuse with TypeScript. Use the contructor like this:
class Product {
constructor(a, b) {
this.a = a;
this.b = b;
}
total() {
return this.a * this.b;
}
}
var product = new Product(2, 3);
console.log(product.total());
Yes, the object can not be a product because the function total is missing. Better use the new operator.
const x = new Product();
x.a = 3;
x.b = 5;
