Conclusion

Quick overview

In this course, we explored TypeScript, its goals, and many of the most used features of the language. At this point, you should be familiar with working with the core of the language, like variables of many types, how to type functions, and use generic code for reusability.

We discovered the multitude of object types and when to use each of them. We dug deep into index type and how to be type-safe while using string to access data. We learned many tricks to narrow down type and how to dynamically map different types with mapping type. We saw how to iterate in many fashions as well as how to manipulate objects and arrays with shorter syntaxes.
