🧠 Go 1.24 Just Got Weak Pointers — Here’s What That Actually Means

The Go runtime now supports weak pointers — giving you smarter memory management, cache handling, and even JavaScript-style weak maps.

In Go 1.24, we got a 🔥 new feature that’s been missing for years:
Weak references that don’t prevent garbage collection.
That means you can now:

• 🧹 Build self-cleaning in-memory caches
• 🧠 Store metadata without keeping objects alive
• 💥 Prevent memory bloat from rarely used blobs
• 🚀 Optimize performance with fewer long-lived allocations

Inside the full post:

• How weak.Pointer[T] works (with real examples)
• What’s going on under the hood (GC internals)
• How finalizers interact with weak refs
• When you should (and shouldn’t) use them
• Performance and memory tips

This is a small but powerful change in Go — and one that can dramatically simplify certain memory-sensitive patterns.
