Suppose there is a Class Vehicle with the following properties:
public id: number;
public modelId: number;
public modelName: string;
Now consider we have an object that looks like this
{id: 1, modelId: 1, modelName: "4"}What is the best way to assign each property of this object to the respective property of the Vehicle class?
Avoiding manual assignment like below:
this.id = obj.id;
this.modelName = obj.modelName;
this.modelId = obj.modelId;
To assign properties, you can use Object.assign method.
Object.assign(new Vehicle(), {
id: object.id,
vehicleName : object.vehicleName,
vehicleId : object.vehicleId
})
Check out this code snippet:
class Vehicle {
public licensePlateNumber?: string;
public manufacturer?: string;
public color?: string;
constructor(details: Vehicle) {
Object.assign(this, details);
}
}
You can create a new vehicle like this:
let car = new Vehicle({licensePlateNumber: "123ABC", manufacturer: "Honda", color: "red"});
