Searching for a way to extract and sum up the numbers enclosed within tags has led me to dead ends. Existing solutions only seem to work partially, possibly due to Javascript not treating the innerHTML content as numerical values.

<p class="prices">10</p>
<p class="prices">20</p>
<p class="prices">30</p>
<p class="prices">40</p>
<p class="prices">50</p>
<script>
let sum = 0;
document.querySelectorAll(".prices").forEach( price =>{
sum += Number( price.textContent );
// sum += parseInt( price.textContent );
});
console.log( sum );
</script>
It's important to note the differences:
Number("2A")
//=> NaN
parseInt("2A");
//=> 2
const sum = 0;
$(".price").each(function(){
sum += parseInt($(this).text())
});
