+# Exports as Tasks
+
+Using the ES2015 module syntax you can use your exports as tasks.
+
+```js
+import gulp from 'gulp';
+import babel from 'gulp-babel';
+
+// named task
+export function build() {
+  return gulp.src('src/*.js')
+    .pipe(babel())
+    .pipe(gulp.dest('lib'));
+}
+
+// default task
+export default function dev() {
+  gulp.watch('src/*.js', ['build']);
+}
+```
