Expenses chart component - vanilla JS

Hey Goran, lovely job here! The component looks great and renders really fast which is great. Here's some points you might like to consider:

• Heading order: In HTML we shouldn't skip heading levels (which I don't think you have done) or use heading levels for presentation purposes (which I think you have done? Using a h2 to make the price font larger for example).

This is important as many people using assistive tech to access your pages will navigate the site based on the heading structure. At the moment this wouldn’t work with your HTML. The would probably need to skip to "my balance" for example, before the actual number.

I approach this by first laying out the page using only HTML and only thinking about the document structure, not design at all, and then once done, I return to the page and use CSS to make things look how they should.

We shouldn’t use headings to make text look BIG or bold. Use them only to set out your document's heading and show the document structure, and then change things up with CSS after that. It's an easy thing to do if you start out with this mindset, and can really help people.

• getElementsByClassName is perfectly valid, but using class names to select elements has really bitten me a few times. They change so often, and get toggled on and off and all sorts of things. I'd suggest perhaps using an id or even a custom data- attribute to hook into the HTML. I do this just as standard now as using classes has given me too many headaches!

Here's a nice article on the approach: https://gomakethings.com/strategies-for-working-with-data-attributes-in-vanilla-javascript/

My only other small suggestions would be to include some error handling with a catch statement in your async functions, and maybe check response.ok is true before continuing. These will both just improve things when things don't work. This property is the best one to check when receiving data (as I understand it!)

I hope this helps and bit and keep up the good work!!

Cheers Dave
