Anonymous self executing functions

Call function is a function that's passed into another function as an argument.

Go functions may be closures.

A "defer" statement invokes a function whose execution is deferred to the moment the surrounding function returns, either because the surrounding function executed a return statement, reached the end of its function body, or because the corresponding goroutine is panicking.

Functions are first class types in Go.

In other words, what an interface tells a type is, "If you have methods that match my functions, then you are my type"

Recursion happens when a function calls itself.

Functions are first class types in Go and hence can be returned from a function just like any other type

When we have a slice of some type, we can pass in the individual values in a slice by using the “...” operator.

We can create a function which takes an unlimited number of arguments Parameter that can accept unlimited number of arguments is known as a “variadic parameter.” We use the lexical element operator ...T to specify variadic parameter of type T
