Was trying to find a very specific text box and as an AngularJS noob, this was the only way I could find it at first. I eventually figured out how to not do this before it ever got committed to production though. :)

function focused(evt, errors) {
	let form = evt.target

	const output = errors.map((error)=> {

		// Find first component with error on form and set focus to it

		let focusedInput = (Object.keys(error) == "phonebookId") ? Object.keys(error) :
			(Object.keys(error) == "phonebook_str") ? Object.keys(error) :
				(Object.keys(error) == "message") ? Object.keys(error) :
					(Object.keys(error) == "image") ? Object.keys(error) :
						(Object.keys(error) == "buttonLink") ? Object.keys(error) :
							(Object.keys(error) == "messageSms") ? Object.keys(error) : false
		return focusedInput.shift()
	})

	const selector = output.shift()
	form.querySelector('[id="' + selector + '"]').focus()

	return selector
}

What can I say... If you plan to work with freelancers with low rate then you should be ready to find it in them code :)

// Is this valid?
function validateStockInItems() {

    return true;
}

Found in a legacy code base for a stock management system. I will be rewriting said system soon.

Why don't be like normal people and use bool() cast?

The for loop that counts to 10, but the last seven elements are completely useless.

The moment an important image ready to be uploaded It's really important that should be checked again and again.

Well, a junior dev here. A cute female QA came to me with a request - "the field for the price already has precision up to 4 decimal places, but we don't like the 4 ugly zeroes, so if the number ends in zeroes, let it have only 2" - she said in the most innocent-like tone ever known to mankind. How easy I mumbled and accepted the task. As she was leaving she added - "oo almost forgot, we also would like it if all the data fields for the price that are shown in the tables also are formatted that way". As I was watching her better side, while she was getting reunited with her QA tribe, I got shivers down the spine. I had a bad feeling about that one, but I wasn't sure why yet. Suddenly as I was getting up to get a cup of coffe, it dawned on me - "this poor excuse for a project is using jqGrid for displaying the data". To wrap things up - I got a quadruple espresso with a shot of Jacky, developers best friend in a time of need, and came up with this piece of art. Enjoy :)
