Go to your EventBrite favourite events page. Scroll to the bottom and load more events until you have a full list. Then paste this code into the developer console. This puts the events in ascending chronological order.

SortEventbriteLikes.js

document.querySelector('.eds-g-group').append(
	...[...document.querySelectorAll('.eds-g-cell.eds-g-cell--has-overflow.eds-g-cell-1-1.eds-g-cell-mn-9-12')]
	.map((elem) => ({
	  date: new Date(elem.querySelector('.eds-text-bs--fixed.eds-text-color--ui-600.eds-l-mar-top-1').innerText),
	  elem
	}))
	.sort((a,b) => -(b.date - a.date))
	.map(({elem}) => elem)
)

Code works on the .co.uk domain as of 09/01/21.

If you have issues with this code. Please check:

• the class selectors are still accurate
• the required results are still the first match on lines 1 and 4 (querySelector first match vs querySelectorAll)
