Writing your first code

When it comes to writing your first code, it’s always good to have some sort of guideline for what to do. In this guide, we’ll show you how to write your first code in Bonzai, introducing the basic syntax and features of the language.

Hello, world!

As with any programming language, we’ll start by writing a program that displays “Hello, world!” on the screen. This is what it would look like in Bonzai:

require "std:natives"

print("Hello, world!")

This program is very simple. It first imports the native functions so that it can use the print function. Then it calls the print function with the text “Hello, world!”, which displays this text on the screen.

To run this program, you can use bpm, which allows you to execute Bonzai scripts. To run the above program, you can create a hello.bzi file with the above contents, then run the following command:

bpm hello.bzi

Variables

Variables are used to store values in a program. In Bonzai, variables are declared using the let keyword. Here’s an example of a variable declaration in Bonzai:

let x = 42

print(x)

In this example, we declare a variable x with the value 42, then print it on the screen. When you run this program, you should see 42 displayed on the screen.

Functions

Functions are used to encapsulate and reuse code. In Bonzai, functions are declared using the fn keyword. Here’s an example of a function declaration in Bonzai :

fn add(x: int, y: int): int => {
  x + y
}

let result = add(3, 4)

print(result)

In this example, we define a function add which takes two parameters x and y of type int and returns the sum of these two parameters. We then call the add function with arguments 3 and 4 and store the result in a result variable, which we then print on the screen.
