When iterating over the keys of an object, this includes not only the keys of the object, but also keys contained in the prototype of that object. It is generally a best practice to check for these keys specifically: var someObject; for (var key in someObject) { if ( ! someObject.hasOwnProperty(key)) { continue; // Skip keys from the prototype. } doSomethingWith(key); } Loading history...
