# Limitations

It is important to note that **Execute JavaScript** has some technical limitations designed to ensure safe usage and dynamic code execution. These restrictions guarantee that scripts are processed efficiently, enabling the creation of customized solutions without compromising the overall system performance. Below, we document the main limitations and supported libraries of this functionality:

1. **HTTP Requests:** HTTP requests are allowed through the [Axios](https://axios-http.com) library, as demonstrated in the following example:

*Example of an HTTP request using Axios:*

```JavaScript theme={null}
const response = await axios.get('https://economia.awesomeapi.com.br/last/USD-BRL');
payload.dollar = response.data;
```

<RequestExample>
  ```javascript Example of HTTP Request Using Axios theme={null}
  const response = await axios.get(
    "https://economia.awesomeapi.com.br/last/USD-BRL"
  );
  payload.dollar = response.data;
  ```
</RequestExample>

2. **Maximum Memory Limit of 128MB:** The **Execute JavaScript** function has a memory limit of 128MB. This ensures efficient processing and prevents system overload.
3. **Maximum Execution Time of 60 Seconds:** Each execution of **Execute JavaScript** is limited to a maximum of 60 seconds. If the script exceeds this time limit, execution will be automatically interrupted to maintain the stability of the runtime environment.
4. **Available Libraries:** In addition to the **Axios** library, **Execute JavaScript** also supports the following libraries: [CryptoJS](https://cryptojs.gitbook.io/docs) and [Moment.js](https://momentjs.com/docs/).
   * **CryptoJS:** A library for hashing, encryption, and decryption — ideal for securely handling sensitive data.
   * **Moment.js:** A library for date and time manipulation, analysis, and formatting, including time zones and interval calculations.
