Understanding Go's Garbage Collector
ℹ️ Disclaimer This post was written while Go 1.25 is the mainstream release. Some implementation details may change as the Go team continues to refine the garbage collector. Still, the ideas here should remain useful for building an intuition about what happens under the hood and why certain design choices exist. If you need the most up-to-date specifics, always refer to the official Go source and release notes.
