# has-own-prop [](https://travis-ci.org/sindresorhus/has-own-prop)
|
|
|
|
> A safer `.hasOwnProperty()`
|
|
|
|
Shortcut for `Object.prototype.hasOwnProperty.call(object, property)`.
|
|
|
|
You shouldn't use `.hasOwnProperty()` as it won't exist on [objects created with `Object.create(null)`](https://stackoverflow.com/a/12017703/64949) or it can have been overridden.
|
|
|
|
|
|
## Install
|
|
|
|
```
|
|
$ npm install has-own-prop
|
|
```
|
|
|
|
|
|
## Usage
|
|
|
|
```js
|
|
const hasOwnProp = require('has-own-prop');
|
|
|
|
const object = Object.create(null);
|
|
object.unicorn = true;
|
|
|
|
object.hasOwnProperty('unicorn');
|
|
//=> 'TypeError: undefined is not a function'
|
|
|
|
hasOwnProp(object, 'unicorn');
|
|
//=> true
|
|
```
