How do Terraform modules help in organizing and reusing infrastructure code?

Terraform modules allow for better organization and reuse of infrastructure code through their support for modularization into self-contained reusable components. Each module would have resources, variables, and outputs that let the developers define their infrastructure once and apply it across environments or projects. This helps organize code and makes large infrastructures much easier to handle. It ensures consistency by standardizing common patterns. Terraform modules promote reusability and maintainability to keep deployments easier and collaboration easy in team environments.
