Templating

Definitions

The practice of defining reusable document structures with placeholder syntax that gets filled with dynamic data at runtime — used for generating HTML pages, emails, configuration files, or code scaffolds from a single template definition.
In plain English: Creating a reusable document with blanks that a program fills in with the right information each time.
Example: "We use Go templating to generate all our Kubernetes manifests from a shared base with per-environment values."
