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>');

true, the $ was in the way! thanks for looking at it!

It's not necessary at all. what are you trying to achieve?

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.
