 When you want to build all files at start and then get only changed files - you can use these snippets:
 
-In callback style:
-
 ```js
-gulp.task('default', function() {
-    return gulp.src('js/*.js').pipe(watch('js/*.js', function(files) {
-        return files.pipe(gulp.dest('.'));
-    }));
-});

         .pipe(watch('js/*.js'))
