# omit

Canonical: https://www.wiki.jodisand.me/snippets/javascript/omit/


Omits the key-value pairs corresponding to the given keys from an object.

- Use `Object.keys()`, `Array.prototype.filter()` and `Array.prototype.includes()` to remove the provided keys.
- Use `Array.prototype.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 }
```
