Astro, WCAG Accessibility, CSS Grid & Animations, Javascript Fetch API

I was wondering how you would get the data from the data.json file and whether you would have a different solution to fetching the data and toggling between that data depending on what stats the user wants to see. In my case I used the JavaScript Fetch API, a function and some if statements to make it all work. Would love to know whether this is considered a good practice or whether there are better ways to approach and solve this. Thanks in advance :)
