JavaScript 写一段最短的代码，用上js所有关键字

void function() {//abcd     do break;while(typeof delete this);    for(var a;;)    if (true)  with(null)    try{}catch(a){}finally{} else throw new 1;       switch(1 in 1 instanceof 1) {      case false:      default:    }    return;  };  // ornew function() {      do break;while(typeof delete this);      for(var a;void 0;)          continue      if (null)          with(0)      try{          switch(1 in 1 instanceof 1) {              case false:              default:throw true          }      }catch(a){}finally{}else return  // console.log("去掉注释可以运行到这里")  };
