We can use the following link to deobfuscate the javascript code

{% embed url="<https://deobfuscate.io/>" %}

But Still I am unable to Understand the Code, because this javascript code is **Packed,** so we need to unpack the code using the following link

{% embed url="<https://matthewfl.com/unPacker.html>" %}

now i can read the code easily and find the enpoints and see how the request is being made

## Javascript Code DeObfuscate by Running it

We can use **developer Console** to actually run the javascript code and we can see what it is doing, we just need to copy the code and then run it in the developer console

&#x20; Below i can see the output of the javascript code in developer console

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://notes.programmersecurity.com/web-pentesting-stuff/pentesting-port-80-443/javascript-deobfuscation.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
