I used jQuery earlier this year.

I am not a web developer I learnt HTML in the 90's (When Frames and Tables were the way to write web pages). I have not kept up to date with current State of the art in web development. I know enough about JavaScript to read source code and kind of understand what it is doing but don't know anything about best practices or the 'proper' way to write it.

I needed to throw together a simple webform to submit a date as one of the inputs. I was having problems getting it to work consistently across different browsers.

One of the issues I was having was I needed the date to be in the Australian date format (DD/MM/YYYY) but one browser (I can't remember which Edge maybe??) kept insisting on using US style dates MM/DD/YYYY it caused me a lot of frustration maybe I just didn't know the correct phrase to search google for but I could not work out how to make the browsers built in calendar picker force the date to be in a specific format.

So I just used the JQuery calendar picker took me two seconds and problem solved.
