How to Distinguish Between Regular Objects and DOM Elements in JavaScript

Determining DOM Object Status in JavaScript

In JavaScript, it's crucial to differentiate between regular objects and DOM elements. This is particularly relevant in scenarios where you need to check whether a given object is a DOM object, which possesses specific characteristics like a "tagName" property.

To effectively resolve this issue, the accepted answer suggests a comprehensive solution. It employs a "try...catch" block to determine if the "tagName" property is read-only. If an exception is thrown while attempting to modify the property, it indicates that the object is likely a DOM element.

Alternatively, a browser-independent approach is to leverage the "instanceof HTMLElement" condition. This method is compatible with modern browsers like Firefox, Opera, and Chrome. However, for older browsers, the code provided in the answer offers a robust fallback mechanism, scrutinizing specific properties that are common among DOM elements.

In summary, this discussion provides valuable insights into determining the nature of JavaScript objects, particularly in the context of differentiating them from DOM elements. The suggested solutions employ a combination of browser-dependent and browser-independent techniques, ensuring reliable results across various platforms.
