javascript - How can I add an option in the beginning?

I have html select,

<select id="myselect">
    <option>1</option>
    <option>2</option>
    <option>3</option>
</select>

I need to add new option in this select. If I try like this:

$('#myselect').appendTo($('<option>my-option</option>')); 

the my-option have added to the end

<select id="myselect">
    <option>1</option>
    <option>2</option>
    <option>3</option>
    <option>my-option</option>
</select>

How can I add an option in the beginning (as first)? Like this:

<select id="myselect">
    <option>my-option</option>
    <option>1</option>
    <option>2</option>
    <option>3</option>
</select>

First, you mean append, rather than appendTo. append adds the content of the parameter to the selection; appendTo appends the selection to the element designated in the parameter.

Second, perhaps intuitively, you can use prepend:

$('#myselect').prepend($('<option>my-option</option>'));
