javascript - 如何通过拆分字符串将数组转换为对象？

Question

我有一个如下所示的数组:

["gender-m", "age-20", "city-london", "lang-en", "support-home"]

我试图生成一个 JSON 对象:

{"gender":"m", "age":"20", "city":"london", "lang":"en", "support":"home"}

我能想到的一种解决方案是使用 FOR 循环来实现它，但我确信对此有优雅的解决方案。任何建议，请帮助我。

你可以拿 Object.fromEntries 使用拆分的键/值对。

var data = ["gender-m", "age-20", "city-london", "lang-en", "support-home"],
    result = Object.fromEntries(data.map(s => s.split('-')));

console.log(result);
