Reflect.construct - typeof

function Point(x, y) { this.x = x; this.y = y }
const p = Reflect.construct(Point, [1, 2])
console.log(p.x, p.y)        // → 1 2
console.log(p instanceof Point) // → true

Reflect.construct() acts like the new operator but as a function, creating a new instance of the target constructor.
