This is a You can play it here - http://play.golang.org/p/ICTtzGIITq out := make(chan string, 1) errs := make(chan error, 1) go f Feb 10, 2018 TL;DR. Despite copying a struct with several fields is slower than copying a pointer to the same struct, returning a struct value may be faster than Feb 1, 2016 Passing by value simplifies escape analysis in Go and gives variable a better chance to be maps pass by reference, but slice not? https://play.golang.org/p/3.

Consider the following example which returns four values, two int values, a float64, and a string: Go has built-in support for multiple return values. This feature is used often in idiomatic Go, for example to return both result and error values from a function. package main: import "fmt" The (int, int) in this function signature shows that the function returns 2 ints.

Last Updated : 01 Aug, 2019. In Go language, you are allowed to return multiple values from a function, using the return statement. Or in other words, in function, a single return statement can return multiple values. The type of the return values is similar to the type of the parameter defined in the parameter list. Two int values and a string value is being returned by this function. As you can see in the function body the parameter is being assigned to the first return value of type int, the second return value is the parameter value multiply by 10 and lastly, a string value indicating that the values has been calculated. Executing these Go functions Go allows you to have a function that returns multiple values.
The optional second return value when getting a value from a map indicates if the key was present in the map. This can be used to disambiguate between missing keys and keys with zero values like 0 or "".

2020-04-05 Run goroutine (asynchronously) and fetch return value from function are essentially contradictory actions. When you say go you mean "do it asynchronously" or even simpler: "Go on! Don't wait for the function execution be finished". But when you assign function return value to a variable you are expecting to have this value within the variable. The (int, int) in this function signature shows that the function returns 2 ints.
A function can return any number of results. The swap function returns two strings.
