What I learned

To day's challenge was a great was to learn how to use the JSON data file to dynamically output a content with DOM manipulation. Also, I learned how to map datas to avoid repeating the same code.

<h1>Some HTML code I'm proud of</h1>

const add_days = (data) => {
	const fund = document.createElement("p");
	fund.style.height = (data.amount + 30) + "px";

	// Find the max amount
	const max = Math.max(...Datas.map(data => data.amount));

	if (data.amount === max) {
		fund.style.backgroundColor = `hsl(186, 34%, 60%)`;
	}

	// the block that shows the amount when hover on graph
	const pop = document.createElement("div");
	pop.classList.add("pop");
	pop.innerHTML = `${data.amount}`;
 	fund.addEventListener ('mouseover', function() {
		pop.style.display = "flex";
	})

	fund.classList.add("bar");
	return (`<li class="day">
	${pop.outerHTML}
	${fund.outerHTML}
	<span>${data.day}</span>
	</li>`)
}
