Answer
Avoid dynamic structures, preallocate buffers, reduce closures, use object pools, minimize large allocations, and tune V8 heap settings to prevent unpredictable GC behavior.
Quick Answer
For memory predictability: pre-allocate large buffers at startup and reuse them (Buffer Pool pattern), use typed arrays (Uint8Array, Float64Array) for fixed-size numeric data (avoids GC), set max heap size explicitly (--max-old-space-size), monitor heap usage and trigger controlled cleanup before GC pressure causes latency spikes.
