javascript - 使用javascript将 "key-value"对数组转换为对象

Question

我有一组键值对

let array = [
  "Social Network: 1",
  "Tasks: 1",
  "Calendar: 1",
  "Journal: 1",
  "Business Contact Manager: 2"
];

我想把它转换成如下所示的对象:

{
  "Social Network": 1,
  "Tasks": 1,
  "Calendar": 1,
  "Journal": 1,
  "Business Contact Manager": 2
}

我怎样才能做到这一点？

Answer 1

您可以使用 .reduce()和 .split()获得所需的输出:

let array = ["Social Network: 1", "Tasks: 1", "Calendar: 1", "Journal: 1", "Business Contact Manager: 2"];

let result = array.reduce((r, c) => {
  let [k, v] = c.split(":");
  r[k] = Number(v);
  return r;
}, {});

console.log(result);
