Typing lesson: Programming in Go language

Programming in Go and touch typing come together naturally in practice. Go has a specific set of syntax rules and symbols that can be a challenge when typing quickly. Touch typing is about typing without looking at the keyboard, and in the context of Go it is important because the language requires accuracy: a missing brace or mistyped operator will immediately cause a compilation error.

What is characteristic about Go syntax?

Go is a compiled language with a clean, minimalistic style. Its source code always starts with a package declaration. Imports are grouped in blocks. Functions are declared with the keyword func and use braces {} to delimit scope. Indentation is not optional-Go enforces formatting using go fmt. The language avoids semicolons in practice, but they are inserted automatically by the compiler at the end of a line. This means that pressing Enter at the right place is not just a typing preference, but a rule in Go.

package main

import "fmt"

func main() {
 fmt.Println("Hello, Go")
}

Symbols to be mindful of

While typing Go code you will encounter certain characters repeatedly. Braces {} appear after every function or control statement. Parentheses () wrap function parameters and calls. Square brackets [] define slices and arrays. Quotes " and backticks ` are used for strings. The short declaration operator := is common when creating variables. Channels introduce the operator <-, which is less familiar on the keyboard and needs extra attention.

Variables and declarations

Unlike some languages, Go distinguishes between declaration with var and short assignment with :=. This operator combines colon and equals, which can be awkward if you are not fluent in typing symbols. Pay attention to how your fingers move here-this operator is everywhere in Go programs.

var count int = 10
message := "typed correctly"

Control structures

Go uses if, for, and switch statements. There is no while. The syntax is compact but requires careful typing of comparison operators ==, !=, <, > and the increment operator ++. Even small typos like = instead of == will break your code.

for i := 0; i < 5; i++ {
 if i%2 == 0 {
 fmt.Println("even")
 }
}

Functions and multiple return values

Functions can return more than one value. That's a powerful feature, but it also means you will type commas inside return lists and assignments often. It's worth practicing until typing result, err := feels natural.

func divide(a, b int) (int, error) {
 if b == 0 {
 return 0, fmt.Errorf("division by zero")
 }
 return a/b, nil
}

result, err := divide(10, 2)

Slices, maps, and composite literals

Square brackets [] and braces {} appear constantly when you work with slices, arrays, and maps. Maps also use colons : to separate keys and values. Together these symbols form some of the trickiest lines to type cleanly if you're not yet comfortable with them.

nums := []int{1, 2, 3}
scores := map[string]int{"alice": 5, "bob": 7}

Structs and methods

Go's struct type groups data. Adding methods requires you to type parentheses for receivers and dots . for field or method access. Once you've done this enough, typing a method receiver feels as automatic as writing the word "func".

type User struct {
 Name string
}

func (u User) Greet() string {
 return "Hello " + u.Name
}

u := User{Name: "A"}
fmt.Println(u.Greet())

Interfaces

Interfaces in Go are satisfied implicitly, without explicit keywords like implements. Defining them means more braces and method signatures to type. It is a small amount of syntax, but it's worth learning to type fluently.

type Stringer interface {
 String() string
}

Concurrency and channels

One of the most distinctive features of Go is the channel operator <-. It doesn't exist in many other languages and it can feel clumsy at first. You will type it both ways: sending ch <- value and receiving value := <-ch. Training your fingers to type this operator smoothly will save you frustration.

ch := make(chan int)
go func() { ch <- 42 }()
value := <-ch

Strings and runes

Go uses double quotes for normal strings, backticks for raw strings, and single quotes for runes. It is easy to confuse them if you are typing quickly, but the compiler is strict. Be especially mindful when switching between ", `, and '.

text := "normal string"
raw := `path\to\file`
r := 'a'

Spacing and formatting

Go enforces a uniform code style. This is helpful, but it also means you need to respect where braces and line breaks go. A common mistake is pressing Enter at the wrong spot, for example after return. Go will complain immediately. Once you get used to its rules, your typing rhythm will become consistent with Go's formatting expectations.

Summary

Programming in Go requires attention to detail in typing. The characters that matter most are braces {}, parentheses (), brackets [], the short assignment operator :=, and the channel arrow <-. These symbols are everywhere in Go code. Practicing them until they feel natural is the key to typing Go programs quickly and without errors.
