javascript - 将对象数组转换为键值对，其中一个值作为键

Question

我有一个像这样的对象数组:

  const arr = [
{
  question_Number: 205,
  question_Text: "Enter Engine Number",
},
{
  question_Number: 497,
  question_Text: "Whether imported?",
},
{
  question_Number: 547,
  question_Text: "Whether goods are new?",
},
{
  question_Number: 206,
  question_Text: "Select Vehicle Condition",
},

];

我想将其转换为键/值对的对象，如下所示:

  const result = {
205: {
  type: "string",
  title: "Enter Engine Number",
},
497: {
  type: "string",
  title: "Whether imported?",
},
547: {
  type: "string",
  title: "Whether imported goods are new?",
},
206: {
  type: "string",
  title: "Select Vehicle Condition",
},

};

如何使用纯 JavaScript 甚至 lodash 实现此结果？

谢谢。

Answer 1

您可以将条目映射到新对象。

const
    data = [{ question_Number: 205, question_Text: "Enter Engine Number" }, { question_Number: 497, question_Text: "Whether imported?" }, { question_Number: 547, question_Text: "Whether goods are new?" }, { question_Number: 206, question_Text: "Select Vehicle Condition" }],
    result = Object.fromEntries(data.map(({ 
        question_Number,
        question_Text: title
    }) => [question_Number, { type: 'string', title }]));
    
console.log(result);

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