Salesforce Commerce Cloud (SFCC) Developer Certification Practice Exam

Using server-side JavaScript in Salesforce Commerce Cloud (SFCC) offers several key advantages, one of which is enhanced security compared to client-side scripting. When code is executed on the server, it is less exposed to potential vulnerabilities that can be exploited by malicious users. This is because server-side scripting processes data and business logic within a controlled environment, limiting the amount of sensitive information sent to the client side.

When using client-side scripts, there's a risk of exposing critical business logic and data, as well as being susceptible to attacks like cross-site scripting (XSS). In contrast, server-side JavaScript maintains a secure boundary that helps protect the application from such threats. Additionally, server-side processing allows for better validation and sanitization of user inputs before any data is passed to the client, further reinforcing security.

While other options highlight various aspects of web development, they do not specifically capture the security benefits that server-side JavaScript provides. For instance, better performance in low-bandwidth environments usually relates more to optimizing the client experience rather than the inherent benefits of server-side processing. Similarly, debugging through browser tools primarily revolves around client-side scripts, and improved accessibility is a broader principle that isn't exclusive to server-side code. Each of these aspects is important, but
