```js // Create random boolean let decision = rand_bool();
if decision {
// Create random number
let random_value = rand();
print(Random number = ${random_value});
} else {
print("Fixed number = 42");
}
// Create array let a = [1, 2, 3, 4, 5];
// Shuffle it! a.shuffle();
// Now the array is shuffled randomly! print(a);
// Sample a random value from the array print(a.sample());
// Or sample multiple values print(a.sample(3)); ```
``rust
// packages::Package implementsassharedmodule`
// which we need to register the RandomPackage
use rhai::{Engine, packages::Package};
use rhai_rand::RandomPackage;
// Create Rhai scripting engine let mut engine = Engine::new();
// Create random number package and add the package into the engine engine.registerglobalmodule(RandomPackage::new().assharedmodule());
// Print 10 random numbers, each of which between 0-99!
for _ in 0..10 {
let value = engine.eval::
println!("Random number = {}", value);
} ```
