We are back again with another effective solution to a simple yet consistent error in LWC.

We know that whenever we mark any Javascript object as @track, Salesforce wraps the object inside creating proxy objects.

However, when we try to print proxy object on the console, the value of the proxy object cannot be seen.

So, in this blog, we share a method through which you see the content of your proxy object just by calling the method and thus print proxy object in LWC.

How to Print Proxy Object

You can also see the content of the proxy object just by keeping another variable @track decorator, but that would need you to constantly keep it in sync every time the content of the original @track object changes.

So, the hassle-free way to see the value of the proxy object is to call the below method.
