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.

Elevify advantages

  • Configure Babel preset-env: target real browsers fast with minimal setup.
  • Optimize polyfills: cut bundle size while keeping legacy browsers fully usable.
  • Build a Babel toolchain: npm scripts, CLI, and source maps for clean demos.
  • Write modern JS: ES6+ syntax, classes, and modules safely transpiled for web.
  • Debug builds: trace transpiled errors, fix missing polyfills, and document setup.
