## What it is
Grunt is a JavaScript task runner that automates repetitive development tasks like minification, compilation, linting, and unit testing via a declarative Gruntfile configuration. It has a large ecosystem of npm-published plugins, including official contrib plugins for file watching, JS minification, and image optimization.

## Use cases
- automate repetitive frontend build tasks
- minify and concatenate JavaScript files
- compress and optimize images for production
- run tasks automatically when files change
- run unit tests and linting as part of a build
- set up a build pipeline for a legacy JavaScript project

## When to choose
- you maintain an existing project already configured with a Gruntfile
- you want a mature, plugin-based task runner with hundreds of available plugins
- you need simple declarative configuration for repetitive tasks like minification or image optimization

## When to avoid
- you are starting a new modern JavaScript project, where npm scripts, Vite, esbuild, or Gulp are more common choices
- you need fast incremental builds or hot module replacement for a modern frontend app
- you prefer writing build logic in code rather than configuration files
