I'm currently working with Angular 2.
Typically, when I specify a type, I start by creating an interface:
interface Product {
name: string,
count: number
}
and then use it like this:
let product: Product;
However, now I need to temporarily define an Object type. Something along the lines of:
let product: Object<name: string, count: number>;
This approach is incorrect. How can I properly achieve this? Thank you
You're getting warm! It's actually known as Object literal type definition and this is what it looks like:
var product: { name : string; count: number; }
// If you prefer, you can also use commas instead of semi-colons
var product: { name : string, count : number }
// And then you can use it just like any other variable
product = { name : 'joe', count : 5 };
Interfaces are amazing because they can be reused in multiple places
