'In for loop of JavaScript, when we iterate, how come it gives result from 0 to 9 in given code when x is a string. It should concat rather [closed]

let x = ""; //Here we have defined x as a string*
    
for (let i = 0; i < 10; i++) {
    x += i + "<br>"; // and here we are adding string to a number so, the result should be concatenation.
}

document.getElementById('demo').innerHTML = x; //

But when we get result, we get numbers from 0 - 9. How Come?

Solution 1:[1]

Because you started with i being 0, and you iterate so long as i is less than 10. So it starts at 0, and once i reaches 10 it exits the loop without executing the code in your loop for the value 10.
