Replaces the names of multiple object keys with the values provided.
|
|
|
|
- Use `Object.keys()` in combination with `Array.prototype.reduce()` and the spread operator (`...`) to get the object's keys and rename them according to `keysMap`.
|
|
|
|
```js
|
|
const renameKeys = (keysMap, obj) =>
|
|
Object.keys(obj).reduce(
|
|
(acc, key) => ({
|
|
...acc,
|
|
...{ [keysMap[key] || key]: obj[key] }
|
|
}),
|
|
{}
|
|
);
|
|
```
|
|
|
|
```js
|
|
const obj = { name: 'Bobo', job: 'Front-End Master', shoeSize: 100 };
|
|
renameKeys({ name: 'firstName', job: 'passion' }, obj);
|
|
// { firstName: 'Bobo', passion: 'Front-End Master', shoeSize: 100 }
|
|
```
