lodash：重命名对象

Question

我想在obj中重命名键：

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：

class Thing a <= SubThing a
  act :: a -> Unit

如果您不熟悉Object.keys(objs).forEach(function (key) { objs[key].original_description = objs[key].description; delete objs[key].description; }); 运营商，请参阅the MDN documentation for delete
