- * 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
