Functional programming 是否有一种方法可以用Ramda覆盖对象中的prop name？

我有一个对象{thing1:{}，thing2:{}}有没有一个方法可以只覆盖一个道具名称，比如{thing1:{}，thing3not2:{}

不确定是否有更快捷/更简单的方法，但是你可以结合assoc来添加新的键，结合dissoc来删除旧的键：

const{curry，assoc，dissoc}=R； const renameProp=咖喱 旧名称、新名称、obj=> dissocoldName，assocnewName，obj[oldName]，obj ; const myTransformation=renamePropthing2，thing3not2； 常量myResult=myTransformation{thing1:{}，thing2:{}； console.logJSON.stringifymyResult，null，4；

Ramda cookbook包含renameKeys函数

下面是从那里抄来的：

/**
 * Creates a new object with the own properties of the provided object, but the
 * keys renamed according to the keysMap object as `{oldKey: newKey}`.
 * When some key is not found in the keysMap, then it's passed as-is.
 *
 * Keep in mind that in the case of keys conflict is behaviour undefined and
 * the result may vary between various JS engines!
 *
 * @sig {a: b} -> {a: *} -> {b: *}
 */
const renameKeys = R.curry((keysMap, obj) =>
  R.reduce((acc, key) => R.assoc(keysMap[key] || key, obj[key], acc), {}, R.keys(obj))
);

并称之为

renameKeys({thing2: 'thing3not2'}, {thing1: {}, thing2: {}})
=> {"thing1": {}, "thing3not2": {}}
