Compiler environment support

NOTE: Compiler support does not dictate the runtime requirements of compiled code.

Officially supported environments

The Babel compiler is only supported in these environments:

  • Modern browsers such as Chrome, Firefox, Safari, Edge etc.
  • Node.js 6 and newer versions

Unsupported environments

This means that any other environment is not supported, this includes but is not limited to:

  • Rhino
  • Nashorn
  • Internet Explorer

NOTE: If Babel works in any of the unsupported environments, it is purely coincidental and has no bearing on future compatibility. Use at your own risk.
