Variables

Variables are declared like so: var message = "hello";

Variables can also be declared without being given a value immediately.

var message; 

message = "hello";

If statements

// if statements
var age = 17;
if (age >= 18) {
	// perform action
} else if (age == 16) {
	// perform alternate action
} else {
	// perform some other action
}

While statements

var index = 0;
while (index < 10) {
	index++;
	// perform action
}

For statements

for (var i = 0; i < 10; i++) {
	// perform action
}

Functions

function factorial(num) {
	return num <= 1 ? 1 : num * factorial(num-1);
}

Anonymous functions

var printHello = function(name) {
	println("hello " + name);
	// no string templates yet
	// println prints to a new line, like Java's System.out.println
}
printHello("world");

Classes

class Square {
	// constructor
	init(length) {
		// fields
		this.length = length;
	}

	// methods
	area() {
		return this.length ** 2;
	}

	perimeter() {
		return 4 * this.length;
	}

	static numSides() {
		return 4;
	}
}

var smallSquare = Square(3);
println(smallSquare.area());
println(Square.numSides);

Inheritance

// inheritance
class Parent {
	speak() {
		println("Hello World!");
	}
}

class Child extends Parent {

}

Child().speak() // Hello World!
