How to get value from the textarea field when it's not equal "".

I tried this code, but when I enter text into textarea the alert() isn't works. How to fix it?

<textarea name="textarea" placeholder="Enter the text..."></textarea>

$(document).ready(function () {
    if ($("textarea").value !== "") {
        alert($("textarea").value);
    }

});

Vanilla JS

document.getElementById("textareaID").value

jQuery

$("#textareaID").val()

Cannot do the other way round (it's always good to know what you're doing)

document.getElementById("textareaID").value() // --> TypeError: Property 'value' of object #<HTMLTextAreaElement> is not a function

jQuery: 

$("#textareaID").value // --> undefined
