Looking for the best way to repeat task in Gulp

gulpfile.js

var destination = imagesBase + '1x/';
var destinationRetina = imagesBase + '2x/';

gulp.task("default", function() {

  spriteAndCompress( destination );
  spriteAndCompress( destinationRetina, 'retina' );

});

function spriteAndCompress( destination, nameExtension ) { 
  var name = 'sprite';
  if( typeof( nameExtension ) !== 'undefined' ) { 
    name += '-' + nameExtension;
  }
                                                                                                                                                                                                                   
  gulp.src( destination + '*.png' )
  .pipe(sprite({
      name: name,
      style: '_' + name + '.scss',
      cssPath: imagesBase,
      processor: 'scss'
  })) 
  .pipe(imagemin({
    optimizationLevel: 5,
    progressive: true,
    interlaced: true
  })) 
  .pipe(gulp.dest( imagesBase )); 
}
