在Javascript中组合两个数组以创建JSON

Question

我有两个数组：

passwordConfirm(control: FormControl): {[s: string]: boolean} {
    if (control.value === this.password) {
        return null;
    }
    return { mismatch: true };
}

如何组合它们并使用数据创建JSON以保存以下内容：

headers=['medium','source', 'name']

rows=[
['direct', 'google', 'demoAccount'],
['direct', 'google', 'demoAccount'],
['direct', 'google', 'demoAccount']
]

Answer 1

您可以使用array#map和array#reduce

＆＃13;

＆＃13;

const headers=['medium','source', 'name'];

const rows=[['direct', 'google', 'demoAccount'],['direct', 'google', 'demoAccount'],['direct', 'google', 'demoAccount']];

var result = rows.map((arr) => {
  return arr.reduce((o, n, i) => {
    o[headers[i]] = n;
    return o;
  }, Object.create(null));
});

console.log(result);
