Demystifying Asynchronous JavaScript

[kulluM]

Hi, I'm getting into Asynchronous JavaScript and need your aid. It's been difficult for me to understand how it works. Here is a bit of code I'm working with:

function fetchData(url) {
    // Async code to fetch data from the URL
}

fetchData('https://api.example.com/data')
    .then(data => {
        // Handle the data asynchronously
    })
    .catch(error => {
        // Handle errors that occur during the async operation
    });

I'm not searching for a quick remedy; I want to fully comprehend the situation. Could you please clarify the typical dangers and misconceptions surrounding asynchronous JavaScript? Also, any advice or best practices for better understanding would be highly welcomed.
Your ideas and examples would be really useful in helping me understand Asynchronous JavaScript.
