Processing data directly in a browser can be more private and secure than processing it on a server in several ways, but it also has its limitations. Here are some key points to consider:

### Privacy and Security Advantages

1. **Data Localisation**: When data is processed in the browser, it doesn't need to be sent to a server. This can reduce the risk of data interception, unauthorized access, or breaches during transmission.

3. **Reduced Exposure**: By not sending data to external servers, you reduce the number of points where data can be exposed or attacked.

### Limitations and Challenges

1. **Computational Limitations**: Browsers are typically less powerful than servers and might not handle large-scale or inten
