What is a Gruntfile and how do I use it?

A Gruntfile is a configuration file for Grunt, a JavaScript task runner. It automates repetitive tasks.

Can you show me a simple example of a Gruntfile?

Sure! Here's a basic Gruntfile.js:

module.exports = function(grunt) {
    grunt.initConfig({
        pkg: grunt.file.readJSON('package.json'),
        uglify: {
            dist: {
                files: {
                    'dist/output.min.js': ['src/**/*.js']
                }
            }
        }
    });
    grunt.loadNpmTasks('grunt-contrib-uglify');
    grunt.registerTask('default', ['uglify']);
};

What tasks can I automate with Grunt?

You can automate tasks like minification, compilation, unit testing, linting, and more using Grunt.
