Why create $pdfCheckbox?

Hi there, I was wondering why it is necessary to first create the const and then append it to the <div> instead of doing it at the same time?

$('#links').append('<label><input type='checkbox'> Allow PDF downloads</label>');

Also, why do we use '$' before the <label> tag, even though we are not selecting it from the HTML?

const $pdfCheckbox = $('<label><input type="checkbox> Allow PDF downloads</label>');

Thanks for your help!

you wrote

$('#links').append$('<label><input type="checkbox"> Allow PDF downloads</label>');

remove the $ after the append and it will work fine, don't know if you will pass the task but you can use it this way

$('#links').append('<label><input type="checkbox"> Allow PDF downloads</label>');

I'm referring to the task of adding the checkbox using jQuery. If I try this code:

$('#links').append$('<label><input type="checkbox"> Allow PDF downloads</label>');

without creating the variable first the checkbox doesn't show.
