Can you explain what is meant by declarative programming style?

The declarative programming style focuses on describing what needs to be done, rather than how to do it. Instead of step-by-step instructions (imperative style), you describe the desired state or outcome, and the system decides how to achieve it.

Example: in SQL, you write a query describing what data you want to retrieve, not how to search for it.

In DevOps, the declarative approach is often used in infrastructure as code (e.g., Terraform, Kubernetes), where you describe the desired state of the infrastructure, and the tool automatically brings the system to that state.
