Tool: Redis Array Playground

    Salvatore Sanfilippo submitted a PR adding a new data type - arrays - to Redis.

The new commands are ARCOUNT, ARDEL, ARDELRANGE, ARGET, ARGETRANGE, ARGREP, ARINFO, ARINSERT, ARLASTITEMS, ARLEN, ARMGET, ARMSET, ARNEXT, AROP, ARRING, ARSCAN, ARSEEK, ARSET.

The implementation is currently available in a branch, so I had Claude Code for web
build this interactive playground for trying out the new commands in a WASM-compiled build of a subset of Redis running in the browser.

The most interesting new command is ARGREP which can run a server-side grep against a range of values in the array using the newly vendored TRE regex library.

Salvatore wrote more about the AI-assisted development process for the array type in Redis array type: short story of a long development.
