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.

Elevify advantages

  • Set up Babel preset-env to target specific browsers quickly with minimal configuration.
  • Optimise polyfills using core-js to reduce bundle sizes while supporting older browsers fully.
  • Create a complete Babel toolchain with npm scripts, CLI tools, and source maps for smooth project demos.
  • Write modern JavaScript with ES6+ features, classes, and modules, safely transpiled for wide web compatibility.
  • Debug transpilation issues by tracing errors, resolving polyfill gaps, and properly documenting your setup.
