If a property is modified in one iteration and then visited at a later time, its value in the loop is its value at that later time. A property that is deleted before it has been visited will not be visited later. Properties added to the object over which iteration is occurring may either be visited or omitted from iteration. In general it is best not to add, modify or remove properties from the object during iteration, other than the property currently being visited. There is no guarantee whether or not an added property will be visited, whether a modified property (other than the current one) will be visited before or after it is modified, or whether a deleted property will be visited before it is deleted.</p> -<div class="note" id="hasOwnPropertyNote"> +<div class="note"> <p>If you only want to consider properties attached to the object itself, and not its prototypes, use <a href="/en-US/docs/JavaScript/Reference/Global_Objects/Object/getOwnPropertyNames">getOwnPropertyNames</a> or perform a <a href="/en-US/docs/JavaScript/Reference/Global_Objects/Object/hasOwnProperty">hasOwnProperty</a> check (<a href="/en-US/docs/JavaScript/Reference/Global_Objects/Object/propertyIsEnumerable">propertyIsEnumerable</a> can also be used).
