Creates a new object, converting each key to a `Symbol`.
|
|
|
|
- Use `Object.keys()` to get the keys of `obj`.
|
|
- Use `Array.prototype.reduce()` and `Symbol` to create a new object where each key is converted to a `Symbol`.
|
|
|
|
```js
|
|
const symbolizeKeys = obj =>
|
|
Object.keys(obj).reduce(
|
|
(acc, key) => ({ ...acc, [Symbol(key)]: obj[key] }),
|
|
{}
|
|
);
|
|
```
|
|
|
|
```js
|
|
symbolizeKeys({ id: 10, name: 'apple' });
|
|
// { [Symbol(id)]: 10, [Symbol(name)]: 'apple' }
|
|
```
