Hey,

I ended up focusing on some improvements for the less important data types and flags. Additionally i added some more tests and updated dependencies because why not.

Anyways feel free to take a look, test and pick what you like. If you don't like some specific change let me know and i'll revert

Cheers!

package.json

Update dependencies

test.js

Added tests for:

• Empty String
• BigInt > 64 bit
• NaN
• Infinity
• Undefined
• Function

test-bench2.js

Added benchmarks for measuring performance of different data types

main.js

Changes:

• separate and clarify flag-only data types
• added flags for: true, false, big bigint, nan, infinity, undefined, function
• changed Buffer.alloc to Buffer.allocUnsafe (faster)
• added support for big bigint (>64bit, stored as hex buffer)
• serialize functions and retrieve actual functions instead of string representation (breaking change)
• store undefined as flag and retrieve actual undefined instead of "undefined" (breaking change)

hash.cc

Added short-circuiting for flag-only types

Performance changes:

• Numbers -> 50% faster writes
• Booleans -> 100% faster writes and 200% faster reads
• Bigint -> 50% faster writes
• Big Bigint -> no longer throws, performance is a bit slower than strings
• Null -> 50% faster writes, 200% faster reads
• NaN -> 100% faster writes, 200% faster reads
• Infinity -> 100% faster writes, 200% faster reads
• Undefined -> 50% faster writes, 200% faster reads
• Function -> now returns an actual function, performance is a bit slower than objects
