in classes/interfaces you can put a ? at the end of the property instead adding undefined does the same thing. Another thing is that interfaces and classes are kinda different (just cause you used it once), and the extends is pretty much everything inheritance is. Everybody hates it with a passion. I'm normally like... if you don't spam it everywhere, in scenarios like this it's a totally fine scenario where it can be used.

type NewRouterContext = RouterContext & { abc: stirng }

Great tip, thanks for sharing.
One question, what VSCode setting / extension are you using to get inline TS errors? :D

Hello, I'm one of your subscriber. Few days back I saw your video where you said that you are using AWS & Casandra database I checked the job posting and nearly 70% of the jobs profiles are under AWS, Casandra. Are you planning on teaching those stuff bro? I know mongodb. Could you please list some of the resources to learn those stuff....

1:48, I belive instead of lising all the types, you can just do typeOf MiddlewareFunction.
