I am proposing that we upgrade to ES11 to stay aligned with the latest JavaScript standards and leverage modern language features such as optional chaining, nullish coalescing, and Promise.allSettled. These enhancements significantly simplify handling complex asynchronous logic, reduce verbose and repetitive code, and improve overall readability and maintainability of our experiment scripts.

While we understand that upgrading is not strictly required to run experiments, adopting ES11 is vital for our growth and development as devs. It enables us to build more robust and reliable A/B tests, accelerate development and iteration cycles, and minimize technical debt. Keeping pace with evolving web technologies ensures our experimentation framework remains scalable and efficient as our testing needs expand.

I would greatly appreciate your consideration of this upgrade.
