What people are saying

One of the things I love about JavaScript is that you can write an almost 10x faster hash table than the standard library if you take care of cache misses and GC:…

I've come across a fair share of zero-alloc implementations of various things, like u/poitrus' zerolog [0] and u/jorangreef's cuckoo-hashtable [1], for instance. Given that JavaScript runs on restrictive clients, it must have libraries in spades for this kind of a thing, but I couldn't find many. I'm really interested in techniques that are generally employed in languages like Java, Golang, Rust, C/++ that are worth translating over to JavaScript, especially now that TypedArrays are a reality. I'm pretty sure there's more to zero-alloc than just Buffers, Object pools, and Recyclables, but I can't seem to find good resources to get started with this.
