javascript - 我可以使用 for 循环吗？ or 函数和 make 对于这个数组来说是最短的和动态的

Question

我是新来的，想在这里学习，所以我想向大家了解一些信息和学习。我们可以为此语句或 if 语句使用 ForEach 吗？？

    var people = [
      [1, 'Dimitri', 'Microsoft'],
      [2, 'Mike', 'Microsoft'],
      [3, 'John', 'Microsoft']
    ];
    
    
    var people2 = `ID : ${people[0][0]}`;
    var people3 = `NAME : ${people[0][1]}`;
    var people4 = `COMPANY : ${people[0][2]}`;
    console.log(people2);
    console.log(people3);
    console.log(people4);
    
    var people5  = `ID : ${people[1][0]}`;
    var people6 = `NAME : ${people[1][1]}`;
    var people7 = `COMPANY : ${people[1][2]}`;
    console.log(people5);
    console.log(people6);
    console.log(people7);
    
    var people8  = `ID : ${people[2][0]}`;
    var people9 = `NAME : ${people[2][1]}`;
    var people10 = `COMPANY : ${people[2][2]}`;
    console.log(people8);
    console.log(people9);
    console.log(people10);

Answer 1

您可以使用一个数组来描述所需的内容，并获取相应索引的数组的值。

var people = [[1, 'Dimitri', 'Microsoft'], [2, 'Mike', 'Microsoft'], [3, 'John', 'Microsoft']],
    keys = ['ID', 'NAME', 'COMPANY'];

people.forEach(a => keys.forEach((k, i) => console.log(`${k} : ${a[i]}`)));

.as-console-wrapper { max-height: 100% !important; top: 0; }

如果你想获得具有名称属性的对象，你可以使用short hand properties

var people = [[1, 'Dimitri', 'Microsoft'], [2, 'Mike', 'Microsoft'], [3, 'John', 'Microsoft']];

console.log(people.map(([ID, NAME, COMPANY]) => ({ ID, NAME, COMPANY })));

.as-console-wrapper { max-height: 100% !important; top: 0; }
