# object.omit [](http://badge.fury.io/js/object.omit)
> Return a copy of an object excluding the given key, or array of keys. Also accepts an optional filter function as the last argument.
## Install
```sh
$ npm i object.omit --save-dev
```
## Usage
```js
var omit = require('object.omit');
```
Pass a string `key` to omit:
```js
omit({a: 'a', b: 'b', c: 'c'}, 'a')
//=> { b: 'b', c: 'c' }
```
Pass an array of `keys` to omit:
```js
omit({a: 'a', b: 'b', c: 'c'}, ['a', 'c'])
//=> { b: 'b' }
```
Returns the object if no keys are passed:
```js
omit({a: 'a', b: 'b', c: 'c'})
//=> {a: 'a', b: 'b', c: 'c'}
```
Returns an empty object if no value is passed.
```js
omit()
//=> {}
```
### Filter function
An optional filter function may be passed as the last argument, with or without keys passed on the arguments:
**filter on keys**
```js
var res = omit({a: 'a', b: 'b', c: 'c'}, function (val, key) {
return key === 'a';
});
//=> {a: 'a'}
```
**filter on values**
```js
var fn = function() {};
var obj = {a: 'a', b: 'b', c: fn};
var res = omit(obj, ['a'], function (val, key) {
return typeof val !== 'function';
});
//=> {b: 'b'}
```
