### omit
|
|
|
|
Omits the key-value pairs corresponding to the given keys from an object.
|
|
|
|
Use `Object.keys(obj)`, `Array.filter()` and `Array.includes()` to remove the provided keys.
|
|
Use `Array.reduce()` to convert the filtered keys back to an object with the corresponding key-value pairs.
|
|
|
|
```js
|
|
const omit = (obj, arr) =>
|
|
Object.keys(obj)
|
|
.filter(k => !arr.includes(k))
|
|
.reduce((acc, key) => ((acc[key] = obj[key]), acc), {});
|
|
```
|
|
|
|
```js
|
|
omit({ a: 1, b: '2', c: 3 }, ['b']); // { 'a': 1, 'c': 3 }
|
|
```
