What will I learn?
This course teaches you to use Babel for writing modern JavaScript that works reliably in older browsers. You will master core concepts, presets, plugins, and config files, then build a smooth workflow with npm scripts, source maps, and automated builds. You will target browsers using @babel/preset-env, optimise core-js and polyfills, debug problems, and complete a full demo project.
