I like decorators as a concept... but there have been a couple different implementations now... the TypeScript version is probably the most broadly used, but there were others before it via Babel (formerly 6to5).
I was an early adopter of the original decorators proposal as well as the F#-style pipeline operators. The more time has moved on and other bits made it into JS proper, I'm far more inclined to stick to what's "in the box"... Have even considered just writing straight JS + ESM (modules). Of course, I also like JSX, though not sure of any proposals of how to get that "in the box" as e4x died on the vine and a lot of other efforts didn't gain much traction either.
