How to get properties of a class with TypeScript?
To get properties of a class with TypeScript, we can create an instance of it and then use Object.getOwnPropertyNames on the instance.
For instance, we write
class A {
private a1 = "";
public a2 = "";
}
const a = new A();
const array = Object.getOwnPropertyNames(a);
to create an A instance.
Then we call Object.getOwnPropertyNames with A instance a to get all the non-inherited properties’ names’ in the array.
