}

This is an experimental feature. You will need to enable experimental features in Babel to get this to compile. Here is a demo with experimental enabled.

To use experimental features in babel you can install the relevant plugin from here. For this specific feature, you need the transform-class-properties plugin:

{
  "plugins": [
    "transform-class-properties"
  ]
}
