Grunt — JavaScript Task Runner for Automation
Grunt is a popular JavaScript task runner used to automate repetitive development tasks such as minification, compilation, testing, and file processing. It helps developers streamline workflows and improve productivity in frontend and backend projects.
What Is Grunt?
Grunt is a command-line tool that executes predefined tasks configured in a Gruntfile (Gruntfile.js). These tasks automate routine operations, allowing developers to focus on writing code instead of manual processes.
Grunt was created by Ben Alman, built with Node.js, and distributed via npm.
