Summary

In this chapter, we discussed the final pieces of TypeScript development. We discussed source maps and how TypeScript uses them to map output JavaScript files back to the original TypeScript file, allowing us to step through our code before compilation. We looked at the different environments in which we could debug our code, whether it be in the browser or the IDE. Finally, we looked at test-driven development and how it allows us to catch errors and unexpected functionality in a reusable and consistent manner. We discussed a large number of topics in a short period of time:

  • Working with the compiler
  • TypeScript's language constructs
  • Object-oriented development with TypeScript
  • Asynchronous module definitions
  • Integrating with external libraries
  • Test-driven development

We built a drawing application using each of these different topics and refined it as our needs changed and knowledge increased. You are now capable of starting a new application in TypeScript and taking it from initial...
