I am dealing with an array of IVisitView objects containing visitDate and clientName information.
export interface IVisitView {
visitDate?: Moment;
clientName?: string;
}
export class VisitView implements IVisitView {
constructor(
public visitDate?: Moment,
public clientName?: string,
) {}
}
Is there a way to transform the array so that the visitDate property is converted to a String type instead of Moment?
Employ the .map() method with a callback function that takes x as an argument and formats its visitDate property to display properly.
interface IVisitView {
visitDate?: Date | string;
clientName?: string;
}
class VisitView implements IVisitView {
constructor(
public visitDate?: Date | string,
public clientName?: string
) {}
}
const createVisit = (date: Date, name: string) => new VisitView(date, name);
const visit1 = createVisit(new Date(), 'UserOne');
const visit2 = createVisit(new Date(), 'UserTwo');
const visit3 = createVisit(new Date(), 'UserThree');
const visitsArr: Array<VisitView> = [visit1, visit2, visit3]
const updatedVisits: Array<IVisitView> = visitsArr.map((v: IVisitView) => {
if (v.visitDate instanceof Date) {
v.visitDate = v.visitDate.toDateString();
}
return v;
});
console.log(updatedVisits);
