Let's go big

Talkat JSConf EU 2017 · on Sunday, 2017-05-07· [javascript, nodejs]
slides:none on file

Claim: JavaScript numbers hit Number.MAX_SAFE_INTEGER (2^53−1) so the talk builds several concrete systems to go beyond that: decimal strings up to to the power of 27 per safe string slot, binary/hex and 16‑bit string slots using Unicode code points, arrays limited by 2^32 - 1 length, and a streaming adder that reads one byte at a time (works on files larger than memory). Sizes quoted: ~268 MB per 16‑bit string, Node default ~1.7 GB, distributed sharding scales by machines; BigInt proposal is noted.
