| 17:46 | <Chris de Almeida> | nicolo-ribaudo: is there a repo yet for Avoid capturing lexical context in indirect eval ? |
| 18:58 | <Justin Ridgewell> | here's a rather stark example:
const unfrozen = Array.from({ length: 10000 }, (_, i) => i);
const frozen = Object.freeze([...unfrozen]);
fn = arr => arr.slice().concat("FIN");
let result;
result = fn(unfrozen); // 10.787 ops/ms
result = fn(frozen); // 1.427 ops/ms
