Проблема с блоками try and catch в js

const box = {
  locked: true,
  unlock() {
    this.locked = false;
  },
  lock() {
    this.locked = true;
  },
  _content: [],
  get content() {
    if (this.locked) throw new Error("Locked!");
    return this._content;
  }
};

function withBoxUnlocked(funct) {
  try {
    console.log(funct);
    box.lock();
  } catch (e) {
    console.log("used catch");
    box.unlock();
    withBoxUnlocked(funct);
  }
}
withBoxUnlocked(box.content);
