Description

We'd like to use babel 6 to build handlebars in debian. Currently build fails with this error

Warning: [BABEL] lib/handlebars.js: Using removed Babel 5 option: base.loose - Specify the `loose` option for the relevant plugin you are using or use a preset that sets the option. Use --force to continue.

Research direction
Investigate the current Babel configuration in package.json and .babelrc. The error indicates a removed Babel 5 option 'base.loose'. Update the Babel config to use Babel 6 compatible presets and plugins. Check the Babel 6 migration guide for changes. Also update any dependencies in package.json to Babel 6 packages. Ensure the build still passes.
