A template for creating a new React Native app using Expo and TypeScript, with a focus on performance and best practices.

/*
  ------------------------------------------------------------------------------
  removeLogs.js
  ------------------------------------------------------------------------------
  This script recursively scans your project directory and removes all 
  console.log statements from JavaScript and TypeScript files.

  WHEN TO USE:
    - Run this script before committing or deploying your code to clean up 
      debugging logs from your source files.

  HOW TO USE:
    1. Adjust the `projectRoot`, `fileExtensions`, and `excludeDirs` variables 
       if needed.
    2. In your terminal, run:
         node template/scripts/removeLogs.js
    3. The script will:
         - Traverse all files in your project (excluding specified directories).
         - Remove all console.log statements, including those in comments and 
           multi-line blocks, from .js, .jsx, .ts, and .tsx files.

  NOTES:
    - The script overwrites files in place.
    - Only console.log statements are removed; other console methods are not affected.
    - Excluded directories (like node_modules, .git, dist, build) are not processed.
    - Review your code after running to ensure no important logs were removed.
