Verify Essential System Commands

Create a robust shell script to check if crucial system commands like `node`, `npm`, `git`, or `docker` are installed before running critical development tasks.

Automate Frontend Build Workflow

Streamline your web development workflow by automating the creation of output directories and execution of frontend build commands (e.g., Webpack, Vite, Gulp).

Basic Web Service Endpoint Health Check

Perform a quick health check on a web service or API endpoint using `curl` in a bash script, verifying its HTTP status code for responsiveness.
