  <p>It is when I change in combo to0 use GruntFile.js.</p>
  
  <p>in node_modules I have installed: <code>grunt-cli, grunt-contrib-jshint, grunt-contrib-uglify, grunt-contrib-watch</code>, they are inside <code>node_modules</code> inside the project level.</p>
  
  <p>My GruntFile.js is:</p>
  
  <pre><code>/// &lt;binding Clean='uglify, watch' /&gt;
  module.exports = function ( grunt )
  {
      var bannerContent = '/*********************************************************\n' +
                          ' my_circle ' +
                          ' ==&gt; Fecha subida:' +
                          ' &lt;%= grunt.template.today("dd-mm-yyyy hh:MM") %&gt;\n ' +
                          '*********************************************************/\n\n';
  
      //definir las tareas
      grunt.initConfig( {
  
          uglify: {
              options: {
                  spawn: false,
                  compress: false,
                  mangle: false,
                  beautify: true,
                  banner: bannerContent
              },
              js: {
                  src: ["Scripts/*.js"],
                  dest: "Scripts/output.min.js"
              }
          }
  
  
      } );
      //para cargar los plugins 
      grunt.loadNpmTasks( 'grunt-contrib-uglify' );
  
      //registrar los plugins a las tareas por defecto. si ejecuto grunt ejecuta por orden los siguientes plugins.
      grunt.registerTask( 'default', ['uglify'] );
  };
