In this section we explain a number of common error codes that users experience in the real world.
Cannot find name ga
You are probably using a third party library (e.g. google analytics) and don't have it
declared. TypeScript tries to save you from spelling mistakes and using variables without declaring them so you need to be explicit on anything that is available at runtime because of you including some external library (more on how to fix it).
Cannot find module 'underscore'
Cannot compile modules unless the '--module' flag is provided
