Overview

The challenge

Users should be able to:

• View the bar chart and hover over the individual bars to see the correct amounts for each day
• See the current day’s bar highlighted in a different colour to the other bars
• View the optimal layout for the content depending on their device’s screen size
• See hover states for all interactive elements on the page
• Bonus: Use the JSON data file provided to dynamically size the bars on the chart

What I learned

I learned how to fetch data from json files and process them. I also used promises + async await for the first time in practise.

async function fetchData() {
    const response = await fetch('./data.json');
    const data = await response.json();
    return data;
}

fetchData()
    .then(data => setData(data))
    .catch(error => {
        console.error(error);
    });

Continued development

In the future I want to work on async JavaScript.

Useful resources

• JSON fetch solution - This helped me when I was trying to import JSON file into JS. I really liked this pattern and will use it going forward.
