The explanation is very good. It is a bit fast and the lecture itself is divided into short segments, so I can see even one more line of typing. 
I am looking forward to the project lecture that will be updated in December.

This is a lecture for those who are starting out with TypeScript. The curriculum is designed to make it easy for even those who don't know the latest JavaScript grammar to learn. Let's learn TypeScript, which can seem difficult, in an easy and fun way from the perspective of a beginner 😄
