This was a pretty nice article although i think there was a mistake in your coding.

    const firstVariable = 'Hello'
    for (let i = 0; i < 6; i++) {
        console.log(firstVariable[i]);
        }
Enter fullscreen mode Exit fullscreen mode

You declared a variable 'i' with the value of 0 but you were now using the keyword to run the loop your code should prolly return an error in ur console log.

Thank you for replying, I am using the i variable which will first be 0, then 1, etc as the index number of the string so that the code will be
console.log(firstVariable[0])
console.log(firstVariable[1])
But I also found that there was an error in my code, i should have used i < 5 because in the last iteration it prints undefined😅
