Why URL hashes are my favorite way to fire events
As a young web developer, I often wondered what the best way to fire events was (for example, to make a link display new content on the page, without reloading). I considered using HTML elements as event handlers, by changing a property when firing an event—but this just seemed too in the way. I needed something out of the way of my HTML.
I then looked at my URL bar, sitting there lonely and unused, and an idea came to me. I would simply add two URL parameters, one named event and one named data! It was perfect!
Or so I thought. Adding URL parameters reloads the page, so this wouldn't work either. But I still thought the URL was the best way to go, and reminded myself of hashes.
For those who don't know, adding hashes to a URL does not reload the page.
I have used this technique ever since then, and it is undoubtedly my favorite. I don't believe this is a usual technique. All I know is that it suits my needs.
window.addEventListener("hashchange", function(hash) {
if (hash === "#profile-19289948") {
...
}
});
Now I'm curious—do other people do something similar? Do other people even know what I'm talking about?

Getting Started With Chart.js: Pie, Doughnut, and Bubble Charts
Mar 15, 2025 am 09:19 AM
This tutorial will explain how to create pie, ring, and bubble charts using Chart.js. Previously, we have learned four chart types of Chart.js: line chart and bar chart (tutorial 2), as well as radar chart and polar region chart (tutorial 3). Create pie and ring charts Pie charts and ring charts are ideal for showing the proportions of a whole that is divided into different parts. For example, a pie chart can be used to show the percentage of male lions, female lions and young lions in a safari, or the percentage of votes that different candidates receive in the election. Pie charts are only suitable for comparing single parameters or datasets. It should be noted that the pie chart cannot draw entities with zero value because the angle of the fan in the pie chart depends on the numerical size of the data point. This means any entity with zero proportion
