    all: {

  }

Gruntfile.js

1. Configuring tasks
2. Loading plugins & tasks
3. Defining task aliases and custom tasks

module.exports = function(grunt) {
  grunt.initConfig({
  pkg: grunt.file.readJSON('package.json'),
  uglify: {
      options: {
        banner: '/*! <%= pkg.name %> <%= grunt.template.today("yyyy-mm-dd") %> */\n'
      },
      build: {
        src: 'src/<%= pkg.name %>.js',
        dest: 'build/<%= pkg.name %>.min.js'
      }
    }
  // ...
  });

  grunt.loadNpmTasks('grunt-contrib-uglify');
  // ...

  grunt.registerTask('task1', 'desc', [taksList]);
  grunt.registerTask('task2', 'desc', function(){
    // ...
  });
  // ...
  grunt.registerTask('default', ['task1', 'task2'])
}
