Javascript 关于文本的两个数组的比较

我有两个数组要比较。因此，我想检查他们是否得到了关于

文本的相等元素：…

。如果等于，则应返回true，否则返回false

  englishData = [
      {"data":"sandwich","text":"Sandwich"},
      {"data":"toast","text":"Cuisine"},
      {"data":"fries","text":"Pommes"},
      {"data":"salad","text":"Salad"},
      ]
  franceData = [
      {"data":"sandwich","text":"Sandwich"},
      {"data":"toast","text":"Kitchen"},
      {"data":"fries","text":"Pommes"}]

到目前为止，我尝试了一个普通的for循环，比如：

for (let i = 0; i < actualData; i++) {
   for (let j = 0; j < plannedData; j++) {
     if (actualData[i].text === plannedData[i].text) {
       return true
     } if (actualData[i].text != plannedData[j].text) {
       continue;
      } 
     }
       return false
  }
 }

如果你想找出共同点，你可以试试这样的方法

englishData = [
  { data: "sandwich", text: "Sandwich" },
  { data: "toast", text: "Cuisine" },
  { data: "fries", text: "Pommes" },
  { data: "salad", text: "Salad" },
];
franceData = [
  { data: "sandwich", text: "Sandwich" },
  { data: "toast", text: "Kitchen" },
  { data: "fries", text: "Pommes" },
];

var res = englishData.filter((ede) =>
  franceData.some((fde) => ede.text === fde.text)
);
console.log(res);

output:
[
  { data: 'sandwich', text: 'Sandwich' },
  { data: 'fries', text: 'Pommes' }
]

您可以使用map（）代替filter来获得每个匹配的true或false

englishData = [
  { data: "sandwich", text: "Sandwich" },
  { data: "toast", text: "Cuisine" },
  { data: "fries", text: "Pommes" },
  { data: "salad", text: "Salad" },
];
franceData = [
  { data: "sandwich", text: "Sandwich" },
  { data: "toast", text: "Kitchen" },
  { data: "fries", text: "Pommes" },
];

var res = englishData.map((ede) =>
  franceData.some((fde) => ede.text === fde.text)
);
console.log(res.join("\n"));

output:
true
false
true
false
