// Defining a function

fn main() {
  print("Hello World"); // Without new line
  println("Hello World"); // With new line
  
  // Prints "Hello, World! - Hello, World! - ... 8 times"
  for(i = 0; i < 10; i++) {
    print("Hello, World!", end=" - ");  // custom end character
  }
}

// Defining variables

let myVar1 = 1; // mutable variable with local scope
// or
myVar2 = 10 // doesn't need keyword to declare. if already declared then changes it
const PI = 3.1415; // im-mutable constant with global scope

// Loops

// for
for ( i = 0; i < 10; i++ ) {
  println(i);
}

// while (not infinite loop)
while (sayHello) {
  print("Hello World");
  break;
}

// loops infinitely with optimizations
loop {
  println("I love Programming");
}

// do-while
do {
  println("Do");
}
while (true) {
  println("while");
  break;
}

// arrays

myArr = [ 1, 2, 3, 4, 5 ];

myNestedArr = [ 1, [ 2, 20, 200, 2000 ], 3, 4, [ 5, 4, 3, 2, 1 ] ]; // arrays within array


// Object
