Important note, If you are using "experimentalDecorators" flag in your tsconfig you'll get a decorator implementation which emulates older stage 2 TC39 decorator proposal and is incompatible with new TS 5 decorators which are based on stage 3 proposal.

Great video. You ran through all the scenarios I would have run to get a feel for the new decorators implementation.

Nice lecture, might take some geekiness to fully understand but clearly explains use cases for the different types of decorators

[MrJorjantas]

Awesome, but where to find all context types? For example, for a function parameter decorator what would be the context type?

[kieronb]

I may have missed it, but neither this video nor the TypeScript docs mention whether you can or cannot pass additional parameters to a class decorator when using stage 3 decorators. Is this possible?

i will just stick to adding properties and methods the old simple way thank you very much, why humans like to complicate things so much is beyond my level

[xqhylas]

I'm using the latest version of TypeScript, and the class decorator only has one parameter, which is different from yours. What's the reason for that?

The video is cool. except I suggest you to be more comfortable while speaking.
