What will I learn?
Babel Course shows you how to write modern JavaScript while delivering reliable experiences in older browsers. You will learn core Babel concepts, presets, plugins, and config files, then set up a clean workflow with npm scripts, source maps, and automated builds. Practice targeting browsers with @babel/preset-env, using core-js and polyfills efficiently, debugging issues, and documenting a small demo project from start to finish.

Your classes are perfect. I purchased the one-year package and finally have the chance to follow several topics I'm interested in without needing to switch platforms... I appreciate everything you do, I've already recommended you to others...
