How to handle custom error types | Smart Go

The video tutorial explores error handling in Go, emphasizing its simplicity and explicit nature. Functions in Go can return multiple values, including an error value, which is nil if no error occurs. The caller checks for errors and handles them accordingly. The tutorial provides an example function that demonstrates this pattern. It also covers creating custom error types using structs, allowing for more flexible error handling. The philosophy of Go's error handling is to be explicit, even if it means being verbose, making the code easier to understand. The video concludes with a summary of these concepts.
