And we wrap up by using these two facts to create extremely powerful conditional type utilities.

Man, really can't thank you enough. The way you walked us through baby steps first and showing that never can be assigned to any other type is what allowed me to understand how it's used in conditionals 🙌🏻

Great channel, really useful, although I have been using TypeScript for a while, I still learning new stuff everyday watching this :) But I just wonder how do you type so fast. I understand you use fast playback, but how do you keep it at constant speed? Looks like it takes exactly same time to type each of the characters...

What is the mechanism when T is just type alias:
type T={koko:string}; //?
Best regards and full respect.
