satisfies operator - New powerful TypeScript feature

satisfies operator, a highlight of the TypeScrip 4.9 release, lets us ensure that some expression matches some type while keeping the specific type of that expression for inference purposes. This prevents a lot of frustrating errors that we had to deal with in the past and makes writing solid TypeScript a lot easier.

Hope that you will join us on this journey! ✍🏻 Marcin on Twitter - https://twitter.com/mkczarkowski ✍🏻 Przemek on Twitter - https://twitter.com/psmyrdek
