GO uses goroutines and channels to handle concurrency efficiently.
GO uses goroutines to achieve concurrency. Goroutines are lightweight threads managed by the Go runtime.
Channels are used to communicate between goroutines. They provide a safe way to pass data between concurrent processes.

GO's 'select' statement allows for ...
defer in Go is used to delay the execution of a function until the surrounding function returns.
Defer is used to ensure that a function call is performed at the end of the surrounding function, regardless of where the defer statement is located.
If there are multiple defers in a function, they will be executed in Last In, First Out (LIFO) order.
Example: func exampleFunc() { defer fmt.Println('First defer'); defer fmt.Pr...
