When we talk about hashes for security purposes, we often naturally think of cryptographic hashes - which are, by design, irreversible. And here we have a dilemma: V8's array index hash is not just a hash - it's a reversible encoding. This enables an important optimization that happens everywhere in V8: for example, in many fast paths that involve string-to-integer conversion, like parseInt("42") or obj["42"] = 1, instead of trying to parse the number from the string (whose content is not necessarily in CPU cache), V8 simply reads the raw_hash_field of the string and extracts the numeric value directly from the hash field. V8 also takes advantage of this encoding in e.g., string equality checks, where it would just compare two integer strings by their hashes. By nature, an irreversible cryptographic hash would break these optimizations and could lead to significant performance regressions in many hot paths.
