TypeScript has been increasingly popular. The typing system helps eliminate most of the coding errors at compile time. Generally, TypeScript costs you a significant amount of time on coding and typing, but later on i will save you much more time on debugging.

This series attempts to facilitate the painful efforts of typing, especially when you are not quite familiar with TypeScript. Thus we will focus on typing and nothing else – anything not specifically related to TypeScript, such as the usage of redux, will be ignored.
