如何将这样的对象转换为非常特定的数组?

Question

{
correct: "Warren Harding",
incorrect: 
0: "Theodore Roosevelt",
1: "Andrew Jackson "
}

我有了这个对象，我想把它变成一个数组包含这样的对象:

[answerOptions: [{answerText: "Warren Harding", isCorrect: true}, {answerText: "Theodore Roosevelt", isCorrect: false}, {answerText: "Andrew Jackson", isCorrect: false}]

我怎么能做到这一点，因为我一直想弄清楚这个问题，但我怎么也弄不清楚。

Answer 1

OP文字几乎是一个有效的对象…

{
correct: "Warren Harding",
incorrect: 
0: "Theodore Roosevelt",
1: "Andrew Jackson "
}

假设嵌套的incorrect对象缺少花括号，那么直接的答案是这样的(请参阅代码片段中正确形成的输入)…

// fix the input
const question = {
correct: "Warren Harding",
incorrect: {  // <- open curly
0: "Theodore Roosevelt",
1: "Andrew Jackson "
} // <- close curly
}
// take a question with the above form and produce an array 
// of { answerText, isCorrect }
function optionsFromQuestion(question) {
return [
{ answerText: question.correct, isCorrect: true },
...Object.values(question.incorrect).map(answerText => {
return { answerText, isCorrect: false }
})
]
}

const answerOptions = optionsFromQuestion(question)
console.log(answerOptions)

Answer 2

假设你的输入对象是这样的:

data = { correct: "Warren Harding",
incorrect: {
0: "Theodore Roosevelt",
1: "Andrew Jackson "
}
} 

你可以这样做:

result = { answerOptions: [
{ answerText: data.correct, isCorrect: true}, 
...Object.values(data.incorrect).map(x => ({ answerText: x, isCorrect: false }))
] }
