为何不输出6个true?

Question

function bouncer(arr) {

  rule=[false,null,0,"",undefined,NaN];

  changed=[];

  for (i=0;i<arr.length;i++){

    dis=false;

    for(j=0;j<6;j++){

      if(arr[i]===rule[j]){dis=true;}

      break;

    }

    console.log(dis);

  }

}

bouncer([false, null, 0, NaN, undefined, ""]);
