Arrow Function

not 100% related, but I'm using ES6 arrow function on this exercise and for some reason arrow function doesn't work on the second time

$('#add-pet').on("click", () => { const $petName = $('#pet-name'); const $petSpec = $('#pet-species'); const $petNote = $('#pet-notes');

const $newPet = $( '<section class="six columns"><div class="card"><p><strong> Name: </strong> ' + $petName.val() + '</p><p><strong>Species:</strong>'+ $petSpec.val() + '</p><p><strong>Notes:</strong>'+ $petNote.val() + '</p><span class="close">Ɨ</span></div></section>' );

$('#posted-pets').append($newPet);

$petName.val(""); $petSpec.val("Dog"); $petNote.val("");

$('.close').on('click', () => { $(this).parent().remove(); }); })

it works as

$('.close').on('click', function() { $(this).parent().remove(); });

is there a specific reason for this ?

Arrow functions don't work exactly like conventional functions.

In this case, the important difference is that arrow functions do not set the value of "this". So if you want to use one as an event handler, be sure to pass and use the event object:

$('.close').on('click', e => { $(e.target).parent().remove(); });

Check the MDN page for more information on how arrow functions are different.
