 ##### Account for TS → Babel issues
 
 ember-cli-typescript v2 uses Babel to compile your code, and the TypeScript compiler only to *check* your code. This makes for much faster builds, and eliminates the differences between Babel and TypeScript in the build output that could cause problems in v1. However, because of those differences, you’ll need to make a few changes in the process of upgrading.
