Disadvantages of the Go language include a less rich ecosystem than other languages, a stricter syntax, and a lack of dynamic typing.

Memory leaks can cause Go program memory to continuously increase by: closing resources that are no longer in use, such as files, network connections, and database connections. Use weak references to prevent memory leaks and target objects for garbage collection when they are no longer strongly referenced. Using go coroutine, the coroutine stack memory will be automatically released when exiting to avoid memory leaks.
