It's a simple calculator with few operators, please take a look and give me feedback on what I can do to shorten it (and run the same way it does with this coding) or ways to improve it (extra coding to make it efficient?)
@Komil I bought my domain from Porkbun because they're fairly cheaper than other domain registrars. As for actually hosting the website, I use Github Pages, mainly due to the fact that it's free. It actually has some really nice features, such as Jekyll, but I have yet to actually use them since that'd ruin the "learning HTML" part. If you're not interested in HTML and just want a nice-looking site, Jekyll is a really good workaround. Using a site builder like Wix will always be easier (and probably look better), but those are expensive, so if you're willing to put in the effort, it's definitely worth it to avoid those.
And, as always, Google is your best friend when it comes to technical stuff like DNS.
