For loop

Question

Are document.getElementById are alway written outside of the executed loop due to the quotation (" ") in the variables text? I thought they were usually written inside the executed loop

for example:

<p id="demo"><p>

<script>

var text = " "; (<--- talking about this)
var food = ["chicken", "salad", "crouton"];
var a;

for (a = 0; a < food.length; a++) {
text += "I love" + food[a] + "<br>";
}

document.getElementById("demo").innerHTML = text;
</script>

Answer 1

Both is possible, you could also do :

var food = ["chicken", "salad", "crouton"];
for (var a=0; a<food.length; a++) {
document.getElementById("demo").innerHTML += "I love " + food[a] + "<br>";
}

Gives you the exact same result.
