如何检查两位数组是否与对象数组的某个部分相同？

Question

How do I check if the array in 'playerChoices' equals, let's say, index 0 in 'test1' array. This is my code as of now. What am I missing? Thanks in advance.

var playerChoices = [1, 3];
const test1 = [{right: 1, wrong: 3}, {right: 2, wrong: 1}, {right: 3, wrong: 2}];

  function check() {
       for (var i = 0; i < test1.length; i++) {
          if (test1[i] !== playerChoices[i]) return false;
    }
      return true;
    };

  if(check()){
       console.log('true');
    };

When you return false inside the loop, it will always return false if the first item does not meet the requirements.

You can use Array.some() to check if any of them is equal as followings:

 const test1 = [{right:1,wrong:3},{right:2,wrong:1},{right:3,wrong:2}]; function check(playerChoices) { // You can use destructuring here to have a more readable code [playerRight, playerWrong] = playerChoices return test1.some(choice => choice.right === playerRight && choice.wrong === playerWrong) }; console.log(check([1, 3])) console.log(check([1, 4]))
