- * Determines whether an object has a property with the specified name.
- * Avoid calling prototype builtin `hasOwnProperty` for two reasons:
- *
- * 1. `hasOwnProperty` is defined on the object as something else:
- *
- *      const options = {
- *        ending: 'utf8',
- *        hasOwnProperty: 'foo'
- *      };
- *      options.hasOwnProperty('ending') // throws a TypeError
- *
- * 2. The object doesn't inherit from `Object.prototype`:
- *
- *       const options = Object.create(null);
- *       options.ending = 'utf8';
- *       options.hasOwnProperty('ending'); // throws a TypeError
- *
- * @param obj A Object.
- * @param v A property name.
- * @see https://eslint.org/docs/rules/no-prototype-builtins
