Summary
In this chapter, we introduced TypeScript and learned why it was created. We learned why type safety and OOP capabilities can be so important for building large apps. Then, we saw some examples comparing dynamic typing and static typing and saw why static typing might be a better way of writing code. Finally, we compared the styles of OOP between the two languages and learned why TypeScript has the better and more capable system. The information in this chapter has given us a good high-level conceptual understanding of the benefits of TypeScript.
In the next chapter, we'll do a deeper dive into the TypeScript language. We'll learn more about types and investigate some of the most important features of TypeScript, such as classes, interfaces, and generics. This chapter should give you a strong foundation for using the various frameworks and libraries in the JavaScript ecosystem.
