Golang program for CRUDD operations on user details

• Use structs to define user details

• Implement functions for Create, Read, Update, Delete operations

• Use a map or slice to store user data

• Handle errors and input validation

• Use packages like 'fmt' and 'bufio' for input/output operations

Arrays have fixed size while slices are dynamic and can grow or shrink.

• Arrays have a fixed size determined at compile time, while slices are dynamic and can change in size during runtime.

• Arrays are passed by value, while slices are passed by reference.

• Arrays use square brackets [] for declaration, while slices use square brackets with a colon [:] to specify a range.

• Example: var arr [3]int = [1, 2, 3] // Array, var slice []int = []int{1, 2, 3} // Slice

Error handling in Golang is done using the built-in error type and the defer keyword.

• Use the built-in error type to represent errors in Go functions.

• Handle errors using if statements or the defer keyword.

• Use the panic function to terminate the program if a critical error occurs.

Concurrency in Golang allows multiple tasks to be executed simultaneously, improving performance and efficiency.

• Goroutines are lightweight threads managed by the Go runtime, allowing for concurrent execution of functions.

• Channels are used to communicate and synchronize data between goroutines, preventing race conditions.

• The 'go' keyword is used to start a new goroutine, enabling parallelism in Go programs.

Troubleshooting site loading issues involves checking connectivity, server status, and browser settings.

• Check internet connectivity: Ensure your device is connected to the internet by testing other websites.

• Verify server status: Use tools like 'Down For Everyone Or Just Me' to see if the site is down for others.

• Clear browser cache: Sometimes, cached data can cause loading issues; clear the cache and try reloading the site.

• Disable browser extensions: Certain extensions can int...read more
