Reflect.construct() - JavaScript | MDN

Reflect.construct() provides the reflective semantic of a constructor call. That is, Reflect.construct(target, argumentsList, newTarget) is semantically equivalent to:

Changing new.target

If newTarget is passed, it changes the value of new.target inside the constructor. The constructed object will be an instance of newTarget, not target.
