Example from the web:

import json

struct User {
    name string
    age  int
mut:
    is_registered bool
}

fn main() {
    s := '[{"name":"Frodo", "age":25}, {"name":"Bobby", "age":10}]'
    mut users := json.decode([]User, s) or {
        eprintln('Failed to parse json')
        return
    }
    for user in users {
        println('$user.name: $user.age')
    }
    println('')
    for i, mut user in users {
        println('$i) $user.name')
        if !user.can_register() {
            println('Cannot register $user.name, they are too young')
            continue
        }
        // `user` is declared as `mut` in the for loop,
        // modifying it will modify the array
        user.register()
    }
    // Let's encode users again just for fun
    println('')
    println(json.encode(users))
}

fn (u User) can_register() bool {
    return u.age >= 16
}

fn (mut u User) register() {
    u.is_registered = true
}

Example from Riju:

fn main() {
	println('Hello, world!')
}

Example from hello-world:

println("Hello World")
