title: Gulp uglify output min.js
body: <p>The js file being compressed is output with the same filename.</p>
  
  <pre><code>gulp.task('compressjs', function () {
    gulp.src('app/**/*.js')
      .pipe(uglify())
      .pipe(gulp.dest('dist'));
  });
  </code></pre>
  
  <p>How can I have it output the file with <code>min.js</code> at the back?</p>
