Summary

The things learned in this chapter will be the basis for continuing our journey into TypeScript. We have discussed a variety of ways in which TypeScript improves the JavaScript development model. TypeScript makes large scale application development easier with the addition of a static typing system and code completion. Visual Studio's intellisense feature brings JavaScript development in line with other languages such as C# and Visual Basic. We briefly discussed the compiler and how it turns TypeScript into deployable JavaScript and created our first application. All of the examples shown moving forward will be using Visual Studio; however, feel free to use your favorite IDE. In the next chapter, we will discuss the different language features provided by TypeScript and how the compiler generates its JavaScript output.
