Code questions

These will help you see the candidate's real-world development capabilities with Draco+++..

What does this simple Draco+++ code do?
let x = 5;
let y = 10;
print(x + y);

What is the output of this Draco+++ code snippet?
for (let i = 0; i < 5; i++) {
  print(i);
}
This code prints the numbers 0 through 4. It's a basic for loop that starts at 0 and increments by 1 each time until it reaches 5, printing the current value of i on each iteration.
What does this Draco+++ code snippet do with the given array?
let arr = [1, 2, 3, 4, 5];
arr.push(6);
print(arr);
This code declares an array with the numbers 1 through 5, adds the number 6 to the end of the array using the push method, and then prints the updated array.
What will be the output of this Draco+++ code related to multithreading?
thread t1 = new thread(() => {
  print('Hello from thread 1!');
});
t1.start();
This code creates a new thread t1 that prints 'Hello from thread 1!' when started. So, the output will be 'Hello from thread 1!'.
