The cheat sheet provides information on Golang variable declarations, including examples of declaring variables with and without initialization, inferring variable types, and declaring and initializing multiple variables at once.

An example of a company using Golang for handling high volumes of geofence-based queries is Uber.

An example of Go variable declaration is:

var age int = 23

In C++, the language is more focused on object-oriented programming rather than functional programming. It also has features such as generic types and a ternary operator.

An example of C++ variable declaration is:

int age = 23;

The GoLang Cheat Sheet was written by Andan H M (andanhm).

Some of the companies using Golang include Google, Docker, Openshift, Dropbox, Netflix, and Soundcloud.

To write a function in GoLang, you can follow the syntax provided in the cheat sheet:

func functionName(parameters) returnType { // function body }

For example: func person(firstName string, lastName string) { // function body }

You can also have functions that return multiple values or named results, as shown in the cheat sheet.

To write a function in GoLang, you can follow the examples provided in the cheat sheet:

1. Function with parameters:

func person(firstName string, lastName string) {}

2. Function with multiple parameters of the same type:

func person(firstName, lastName string) {}

3. Function with a return type declaration:

func person() int {
    return 23
}

4. Function returning multiple values at once:

func person() (int, string) {
    return 23, "vinay"
}

5. Function with named results:

func person() (age int, name string) {
    age = 23
    name = "vinay"
    return
}

6. Function returning a function:

func person() func() (string, string) {
    area := func() (string, string) {
        return "street", "city"
    }
    return area
}

You can use these examples as a reference to write your own functions in GoLang.
