What will I learn?
This course teaches you to use Babel for writing modern JavaScript that works reliably in older browsers. You'll master core concepts, presets, plugins, and configs, then build efficient workflows with npm scripts, source maps, and automated builds. Hands-on practice includes targeting browsers with @babel/preset-env, smart polyfill use with core-js, debugging, and completing a full demo project.
