// subclass
class B extends A {
    
    // ⭐ replace `super.method()`
    method() { log(`b.method() runs.`) }     // "b.method() runs."

    // ⭐ extend `super.method()`
    method() {
        log(`b.method() runs first, then:`)  // "b.method() runs first, then"
        super.method();                      // "a.method() runs."
