Parcel
In plain terms
A zero-configuration web application bundler.
Going deeper
Parcel bundles web assets with little or no configuration, automatically handling transforms and dependencies. It targets ease of use over Webpack's flexibility.
Under the hood
Auto-detects and installs needed transforms; good for quick projects, though Vite has taken much of its niche.
Examples
Quick prototypes, small apps, zero-config bundling, demos.
Think of it like...
Like a self-setting-up moving service: point it at your stuff and it packs everything correctly.
