Definitions
Software that has become excessively large, slow, or resource-hungry relative to its functionality. Also: unwanted pre-installed applications on new devices that nobody asked for and everyone uninstalls.

In the context of web development, bloatware describes websites and apps that ship megabytes of JavaScript for simple functionality. A 'bloated' bundle often results from importing entire libraries to use a single function.
Example: 'The landing page ships 4MB of JavaScript for a contact form and a hero image. That's web bloatware — it could be 50KB of HTML.'
