Explanation of each folder/file:

• bin/: Contains the executable script for the command-line interface (CLI). You can name it whatever you like; here, it's named "grepjs."

• lib/: Holds the main functionality implementation. In this case, it's named "grep.js." This is where you put the code that performs the grep-like functionality.

• test/: Contains test files for your project. It's a good practice to include tests for your code. The test file is named "test_grep.js" here.

• package.json: Configuration file for Node.js projects. It includes information about your project, dependencies, scripts, etc.¹.

• README.md: Documentation for your project. This is where you can provide information about the project, how to install it, and how to use it.

• LICENSE:² Include a license file that specifies the terms under which your software is distributed.

• .gitignore: Specifies files and directories that should be ignored by version control (e.g., node_modules, build artifacts).

This structure provides a good separation of concerns and makes it easy to expand your project in the future. You can further break down the lib/ folder if your application becomes more complex.
