BENCHMARKING THE PERFORMANCE OF CSS @PROPERTY

This article benchmarks the performance of CSS @property, a new feature that allows developers to register custom CSS properties. PerfTestRunner was used to measure the performance of different types of properties, including regular properties, unregistered custom properties, and registered custom properties with different inheritance settings. The results show that registering a custom property with @property comes at a slight performance cost, but using `inherits: false` when registering a custom property can significantly improve performance.

MY NEGATIVE VIEWS ON RUST

Rust has a reliance on "magical sugar" constructs, which lead to cryptic compile errors and make the language harder to learn. The language's focus on efficient memory representation and its insistence on no garbage collection are also detrimental, as it forces developers to grapple with low-level details that don't always translate to real-world performance gains.
