How to manually trigger garbage collection using runtime.GC() in Golang?

To manually trigger garbage collection in Go using the runtime.GC() function, follow these steps:

  1. Import the runtime package at the top of your Go program:

    import "runtime"
  2. Call the runtime.GC() function to manually trigger garbage collection in your code whenever you want to clean up unused memory:

    func main() { // ... // Trigger garbage collection manually runtime.GC() // ... }

By calling runtime.GC(), the garbage collector is invoked immediately, and any eligible memory that is no longer referenced is reclaimed.

Note that while you can manually trigger the garbage collector, it is generally not necessary as Go has an automatic garbage collector that runs in the background. The Go runtime manages the memory automatically, so explicit manual garbage collection is rarely needed.
