Quick Answer
What is a .gitignore file?
// Answer
A .gitignore file tells Git which files and folders to ignore — things like build output, dependencies (node_modules), environment files, and editor settings that shouldn’t be committed. Keeping these out of version control keeps your repository clean and avoids leaking secrets.
