Functions

Functions let you group a block of code together, give it a name, and run it whenever you want. This keeps your code clean and prevents you from writing the same logic twice.

Hello World​

This function takes a parameter (a name) and prints a greeting message in the console.

bamboo greet = fn(name) {
    echoln("Hello, " + name);
};

// Call the function
greet("World");
greet("Aprim");

// Output:
// Hello, World
// Hello, Aprim

Returning a Value​

Use the return keyword to send a calculated value back to where the function was called.

bamboo add = fn(num1, num2) {
    return num1 + num2;
};

// Call the function and save the result in a variable
bamboo total = add(12, 8);

echoln("Total is " + str(total));

// Output:
// Total is 20

Check Even or Odd​

You can combine functions with iff and otherwise to return different values depending on the inputs.

bamboo isEven = fn(num) {
    iff (num % 2 == 0) {
        return true;
    } otherwise {
        return false;
    }
};

bamboo number = 7;

iff (isEven(number)) {
    echoln(str(number) + " is even!");
} otherwise {
    echoln(str(number) + " is odd!");
}

// Output:
// 7 is odd!
