TypeScript can check them at build time and emit plain positions instead. For 100 buffer records, that's 4% of the script's memory rather than 11%, with reads about 12 times as fast. typescript slua build https://nya.place/posts/compact-objects https://nya.place/posts/compact-objects Tue, 29 Sep 2026 00:00:00 GMT A shared metatable lets code read arrays and buffers by field name. In the test, 100 records use about 43% of the script's memory with named fields, or 11% as buffers with names. slua memory metatables https://nya.place/posts/table-capacity https://nya.place/posts/table-capacity Sun, 27 Sep 2026 00:00:00 GMT An appended 285-entry list in SLua uses 384 slots at 16 bytes each.
