> Map.prototype.at() & Set.prototype.at() Stage: 0 (with a dream) Author: Someone tired of converting Maps to arrays Help wanted: Champion, spec writers, emotional support The Pitch Arrays and strings got .at() in ES2022. Negative indices. Clean syntax. No more arr[arr.length - 1] nonsense. Maps and Sets are ordered too. They deserve the same dignity.

It makes them more useful for building caches with eviction policies. For example, you can build an LRU cache by deleting and re-inserting items when they are accessed. While implementing the SIEVE algorithm in JS, I noticed that an .nth() method would be handy. Without it, I need to track insertion order in a seperate array, OR copy the ke…
