Disallow use of Object.prototypes builtins directly (no-prototype-builtins)
In ECMAScript 5.1, Object.create
was added, which enables the creation of objects with a specified [[Prototype]]
. Object.create(null)
is a common pattern used to create objects that will be used as a Map. This can lead to errors when it is assumed that objects will have properties from Object.prototype
. This rule prevents calling Object.prototype
methods directly from an object.
Rule Details
This rule disallows calling some Object.prototype
methods directly on object instances.
Examples of incorrect code for this rule:
/*eslint no-prototype-builtins: "error"*/
var hasBarProperty = foo.hasOwnProperty("bar");
var isPrototypeOfBar = foo.isPrototypeOf(bar);
var barIsEnumerable = foo.propertyIsEnumerable("bar");
Examples of correct code for this rule:
/*eslint no-prototype-builtins: "error"*/
var hasBarProperty = Object.prototype.hasOwnProperty.call(foo, "bar");
var isPrototypeOfBar = Object.prototype.isPrototypeOf.call(foo, bar);
var barIsEnumerable = {}.propertyIsEnumerable.call(foo, "bar");
When Not To Use It
You may want to turn this rule off if you will never use an object that shadows an Object.prototype
method or which does not inherit from Object.prototype
.
