Aim of the puzzle: Use a classic for loop to access every 3rd element in an array.
Walk through of solution: The tacos array is imported from additional code. It is shuffled before every code run, so the array should have a different order of elements each time.

The classic for loop declares the looping variable i and sets its value to 0. After each iteration, the operation i += 3 will update i by 3. The iteration will continue as long as i < tacos.length is true.

Inside the code block, we can access and print out the current element in the tacos array by using i for its index.
Sample code solution:

import { tacos } from 'grasshopper.taqueria';

for (let i = 0; i < tacos.length; i += 3) {
    console.log(tacos[i]);
}

Additional Code (hidden code that runs before the puzzle’s code):

let _tacos = [
    'al pastor', 
    'carnitas', 
    'lengua', 
    'pollo', 
    'carne asada', 
    'tripas', 
    'chorizo', 
    'barbacoa', 
    'arroz con frijoles'
];
        
function shuffle(array) {
    for (let i = array.length - 1; i > 0; i--) {
        let j = Math.floor(Math.random() * (i + 1));
        [array[i], array[j]] = [array[j], array[i]];
    }
    return array;
}

let tacos = shuffle(_tacos);
