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) or it can have been overridden.

Install

$ npm install has-own-prop

Usage

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
