What is the primary use case of the 'recover()' function in Go?
- To cause a panic
- To handle panics and resume normal execution
- To recover lost data
- To terminate the program
The primary use case of the recover() function in Go is to handle panics and resume normal execution. When a panic occurs in a deferred function, the recover() function can be used to capture the panic value and allow the program to gracefully recover from the panic, preventing it from terminating abruptly. This is particularly useful for scenarios where it's essential to maintain the stability and availability of the program despite encountering unexpected errors.
