How to count the number of option tags in a select tag in JavaScript?

For instance, we write
<select data-attr="dropdown" id="input1">
<option value="Male" id="Male">Male</option>
<option value="Female" id="Female">Female</option>
</select>
to add a select drop down.
Then we write
const len = document.getElementById("input1").length;
to select the drop down with getElementById.
And we get the number of options with the length property.
