Prefer use of Object.hasOwn over Object.prototype.hasOwnPrototype (prefer-object-has-own)

When Object.prototype.hasOwnPrototype.call is used, this rule requires using the Object.hasOwn instead. Object.hasOwn is a syntactic sugar and makes the code cleaner.

Rule Details

Examples of incorrect code for this rule:

/*eslint prefer-object-has-own: "error"*/
Object.prototype.hasOwnProperty.call(obj, "a");

({}).hasOwnProperty(obj,"a");

let a = Object.prototype.hasOwnProperty;

Examples of correct code for this rule:

/*eslint prefer-object-has-own: "error"*/

Object.hasOwn(obj, "a");
