I am working on a class that has private properties:
class A implements IA {
private id: number;
private name: string;
constructor(obj: IA) {
// Need to assign properties from obj here
}
}
My goal is to pass an object of type IA with initialized values when creating an instance of A, and only update the properties in the class that I provide.
For example: new A({id: 1}) or new A({id: 1, name: "O"})
Can anyone guide me on how to achieve this in TypeScript?
To easily achieve this, you can utilize the Object.assign method. This function will only duplicate the specified fields provided in the constructor parameter.
interface IA{
id? : number;
name? : string
}
class A {
private id: number;
private name: string;
constructor(obj: IA) {
Object.assign(this, obj)
}
}
Please note: I have omitted the 'implements' keyword from the class as private fields cannot be used to implement an interface.
