Upon migrating from Gulp 3 to Gulp 4, we see the following error ... AssertionError [ERR_ASSERTION]: Task function must be specified According to https://www.liquidlight.co.uk/blog/how-do-i-update-to-gulp-4/, the second argument of gulp.task() has to be a task function which can be generated by series() or parallel() function. Additionally, we switch from package babel-preset-es2015 to @babel/preset-env with target and debug options included as a showcase.

Hello Ryan,
Thank you for a very inspirational video tutorial on youtube.
I learn a lot from it. Unfortunately, the tutorial uses Gulp 3 and Babel 6.
So I played with it a little bit by migrating your project to Gulp 4 and used @babel/preset-env instead of babel-preset-es2015.
Regarding @babel/preset-env, I also added targets and debug option to help study which versions of browsers are included.
I really like you video. It would be great if you can upload a new one for Gulp 4 and Babel 7. :-)
