To prevent nil pointer dereferences in Go, apply defensive coding patterns by checking pointers before access and safely initializing maps and slices. This prevents common runtime panics and silent data corruption.

Avoid slice aliasing and concurrent map access bugs by copying slices when necessary and synchronizing map access. These defensive patterns prevent silent data corruption during concurrent operations.

Handle numeric conversions safely by checking bounds before casting, and perform float comparisons using an epsilon value. This prevents overflow and silent equality errors in calculations.

Use defer correctly for resource management by ensuring proper cleanup execution and implementing patterns to prevent goroutine leaks. This avoids exhausting connections and memory during execution.

Yes, you can review existing Go code for safety issues by applying these defensive guidelines during code reviews and static analysis. It is ideal for auditing libraries for nil, slice, and map safety.
