Tell about memory leaks in Go.

In Go, memory leaks occur when objects remain reachable for the garbage collector even though they are no longer needed by the program. This can happen due to:

• Global variables or slices that continue to reference objects.
• Closures capturing variables that are not released.
• Channels or goroutines that block and hold references.

Example: if you create a slice and do not nullify references to its elements, the garbage collector cannot free the memory.

To detect leaks in Go, you can use the pprof package and memory profiling tools. It is important to carefully manage the lifetime of objects and avoid unnecessary references so that the garbage collector can efficiently free memory.
