      Nice write-up! We should talk about the chicken-egg problem here: ``` // when BigInts are optimised in JavaScript, we could use a BigInt64Array. ``` IMHO it’s the other way around.

      Ideally, JS engines optimize for real-world coding patterns. By using modern features in an idiomatic way, you force JS engines to improve their performance for those patterns.

          TL;DR Please don’t avoid modern features by default. By default, use them whenever it makes sense to you. If a particular pattern turns out to be a perf bottleneck, let us know.

          "idiomatic way" is code for "write like everyone else"? how does everyone else code? Or, does it mean "like engine developers intend you to write it"? Is there a convention (like those for airbnb eslint)? A checklist?

          It means (or at least, I meant) write code that makes sense to you. Optimize for readability. Don’t try to outsmart JavaScript engines — they’re constantly changing and improving.
