Call constructor on TypeScript class without new

Question

In JavaScript, I can define a constructor function which can be called with or without new:

function MyCl         


        

Answer 1

My workaround with a type and a function:

class _Point {
    public readonly x: number;
    public readonly y: number;

    constructor(x: number, y: number) {
        this.x = x;
        this.y = y;
    }
}
export type Point = _Point;
export function Point(x: number, y: number): Point {
    return new _Point(x, y);
}

or with an interface:

export interface Point {
    readonly x: number;
    readonly y: number;
}

class _PointImpl implements Point {
    public readonly x: number;
    public readonly y: number;

    constructor(x: number, y: number) {
        this.x = x;
        this.y = y;
    }
}

export function Point(x: number, y: number): Point {
    return new _PointImpl(x, y);
}
