Arguments
string
required
The array key.
Response
The number of slots containing values, or zero for a missing key.
await redis.arset("readings", 1000, "sample");
console.log(await redis.arcount("readings")); // 1
console.log(await redis.arlen("readings")); // "1001"
ARCOUNT
Count the occupied slots in an array.
await redis.arset("readings", 1000, "sample");
console.log(await redis.arcount("readings")); // 1
console.log(await redis.arlen("readings")); // "1001"
For sparse arrays, this differs from ARLEN, which returns the highest occupied index plus one.
See the server command reference for protocol details.
