REPL-Driven Development Workflow

• Start with small, fundamental functions:
• Identify the core features or functionalities required for your task.
• Break each feature down into the smallest, most basic functions that can be developed and tested independently.
• Write and test in the REPL:
  • Write the code for each small function directly in the REPL (Read-Eval-Print Loop).
  • Test it thoroughly with a variety of inputs, including typical use cases and relevant edge cases, to ensure it behaves as expected.
• Integrate into source code:
  • Once a function works correctly in the REPL, move it from the REPL environment into your source code files (e.g., within appropriate namespaces).
• Gradually increase complexity:
  • Build upon tested, basic functions to create more complex functions or components.
  • Compose smaller functions together, testing each new composition in the REPL to verify correctness step by step.
• Ensure dependency testing:
  • Make sure every function is fully tested in the REPL before it is depended upon by other functions.
  • This ensures that each layer of your application is reliable before you build on it.
• Use the REPL fully:
  • Use the REPL as your primary tool to experiment with different approaches, iterate quickly, and get immediate feedback on your code.
• Follow functional programming principles:
  • Keep functions small, focused, and composable.
  • Use Clojure's functional programming features—like immutability, higher-order functions, and the standard library—to write concise, effective code.

How to Evaluate Code

Bottom-up Dev Loop

1. Write code into a file.
2. Evaluate the file's namespace and make sure it loads correctly with:
