lodash:重命名对象中的键

Question

我想重命名obj中的键,由此:

objs = {
  one: { description: "value", amount: 5, value: { description: "value desc", identifier: "some text"} },
  two: { description: "value", amount: 5, value: { description: "value desc", identifier: "some text"} }
}

进入这个:

objs = {
  one: { original_description: "value", amount: 5, value: { description: "value desc", identifier: "some text"} },
  two: { original_description: "value", amount: 5, value: { description: "value desc", identifier: "some text"} }
}

Answer 1

你真的不需要lodash.您需要做的是使用旧值在对象上创建一个新键,然后删除旧键.例如:

Object.keys(objs).forEach(function (key) {
    objs[key].original_description = objs[key].description;
    delete objs[key].description;
});

如果您不熟悉该delete运算符,请参阅MDN文档delete
