Code Runner

Noun · Development

Definitions

  1. A tool or environment used to execute code snippets, scripts, or programs quickly, often inside an editor, sandbox, notebook, or test harness. Code runners are helpful for experimentation and demos, but they may differ from production runtimes in subtle but important ways.

    In plain English: A tool or environment that runs code for quick testing or experimentation.

    Example: "The playground's code runner was great for trying out expressions, but the final service still needed integration testing against the real runtime and database."
