When working with selects, there is the following
feature: the variable that stores the reference
to the select is an array, the elements of which
are the option
tags. This means that this
variable can be looped over:
let select = document.querySelector('#select');
for (let option of select) {
console.log(option);
}
Well, or just turn to the item with the desired number:
let select = document.querySelector('#select');
console.log(select[0]);
Loop through all the items in the list and
add the value of its value
attribute
to the end of the text of each item.
