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
