Variables (Remembering)

Telling the computer to remember something is called a variable.

How to remember things in Go

In Go, you can do it in a short and clear way.

x := 2026
y := "Hello, Go!"

In plain English:

Remember that x is 2026
Remember that y is "Hello, Go!"

The symbol := is a magic shortcut that means “create a name and put a value in it right away.”

Say what you remembered

Let us check if the computer remembered correctly.

package main

import "fmt"

func main() {
    x := 2026
    y := "Hello, Go!"

    fmt.Println(x)
    fmt.Println(y)
}

Result:

2026
Hello, Go!

What can Go remember?

Go is very strict and clearly separates the types of things it remembers.

number := 2026        // integer (int)
decimal := 3.14       // float (float64)
text := "Hello"       // string (string)
truth := true         // boolean (bool)

Now you know how to store and retrieve information in Go.
