Grunt is a JavaScript task runner that automates repetitive tasks like minification, compilation, unit testing, and linting. It's a tool for masochistic developers who enjoy subjecting themselves to mind-numbing configuration files and cryptic error messages.

How to use it in a sentence

• "I spent all day debugging my Grunt build script, only to realize I had a typo in the configuration file. I could've been writing actual code instead of this 'gruntwork'."

• "My tech lead insisted on using Grunt for our new project, saying it would 'streamline our workflow'. More like streamline my path to carpal tunnel syndrome from all the extra typing."
