this one can be good for checking if an element exists before doing something with it and can stop warning messages if you are running the script on multiple pages.

if ($('#mydivid').length) {
console.log('div found... ');
}

Our brains are wired to find things we are looking for - if your always cynical or waiting for things to go wrong, then your life will reflect that. On the other hand, having a positive outlook on life will bring you joy and provide you with inspiration when you least expect it ☀️🍉🌴
