Javascript需要修复代码

Question

这是我的代码

function howManySundays(num,startDay){
  let Days = ["Monday","Tuesday","Wednesday","Thursday","Friday","Saturday","Sunday"];
  for(let i = 0 ; i < num ;i++){
    var value = [];
    value.push(Days[i%7])
    console.log(value)
  }
}
howManySundays(9,"Sunday");

这是代码

的结果

[ 'Monday' ]
[ 'Tuesday' ]
[ 'Wednesday' ]
[ 'Thursday' ]
[ 'Friday' ]
[ 'Saturday' ]
[ 'Sunday' ]
[ 'Monday' ]
[ 'Tuesday' ]

如何在数组中找到重复项？

Answer 1

这会对你有帮助吗？

function howManySundays(num,startDay){
  let Days = ["Monday","Tuesday","Wednesday","Thursday","Friday","Saturday","Sunday"];
  let i = 0;
  while (num > 0) {
    console.log(i, Days[i])
    i++;
    if(i == 7) i = 0;
    num--;
  }
}
howManySundays(9,"Sunday")
