Hello World
package main
import "fmt"
func main() {
	fmt.Println("Hello World!")
}
 
println('Hello World!')
Slice initialization
numbers := []int{1, 2, 3, 4}
 
numbers := [1, 2, 3, 4]
Add an element to a slice
numbers = append(numbers, 5)
 
numbers << 5
Printing a slice
fmt.Println(numbers)
 
println(numbers)
Filtering a slice
even := make([]int, 0)
for _, num := range numbers {
	if num % 2 == 0 {
		even = append(even, num)
	}
}
 
even := numbers.filter(it % 2 == 0)
Checking if a slice contains an element
contains := false
for _, num := range numbers {
	if num == x {
		contains = true
		break
	}
}
 
contains := x in numbers
Reading a file
import (
	"io/ioutil"
	"log"
)
b, err := ioutil.ReadFile(path)
if err != nil {
	log.Println(err)
	return
}
text := string(b)
 
import os
text := os.read_file(path) or {
	eprintln(err)
	return
}
Testing a function
package greeter_test
import (
	"testing"
)
func TestHello(t *testing.T) {
	if Hello() != "Hello" {
		t.Fatalf("Hello() failed")
	}
}
 
fn test_hello() {
	assert hello() == 'hello'
}
