Grunt is a JavaScript task runner for managing tasks during development. Grunt runs in the Node.js environment and provides a quick solution over other build tools because of the huge ecosystem of plugins, which add additional functionality to the command line. Grunt is an alternative to Ant or Make.

Grunt tasks are JavaScript modules that utilize the Node and Grunt API to add automation in just about anything; tasks are installed using Node's package manager npm.

Grunt eases the management of a project by performing various tasks and can help manage a project's life cycle from development to production.
