Assignment: Data Processing CLI

Description

Data Processing Toolkit — an interactive command-line application that performs various useful data processing operations. This tool works as a persistent Node.js process that accepts commands.

Technical requirements

• Any external tools and libraries are prohibited
• Use 24.x.x version (24.10.0 or upper) of Node.js
• All file operations must use Streams API for efficiency (do not read entire files into memory)
• Prefer asynchronous API whenever possible
• The program should be an interactive REPL (Read-Eval-Print Loop)
• File paths in commands can be relative or absolute

1. Clone this repository

   git clone https://github.com/zhannach/data-processing-cli.git
   cd node-nodejs-fundamentals

2. Install dependencies (if any added in the future)

   npm install

3. Start checking the tasks

   Each file in the src/ directory contains a function template with comments describing what needs to be implemented.
