Extending the Error class errors when trying to overwrite the `name` property

XMLWordPrintable

      Example:

      class MyError extends Error {
    constructor() {
        super();
        this.name = "MyError";
    }
}

// Throws a TypeError
const e = new MyError();

      If I wrap the `this.name` on a `try/catch` block this works (of course, `name` is not set).

      I think this is something specific on the Error implementation, because this does not throw:

      class A {
    constructor() {
        this.name = "A";
    }
}

class B extends A {
    constructor() {
        super();
        this.name = "B";
    }
}

// Does not throw
const e = new B();
