How to use JSON.stringify to output JSON to a div in a pretty print way with JavaScript?
To use JSON.stringify to output JSON to a div in a pretty print way with JavaScript, we call it with a 3rd argument.

<pre id="json"></pre>
to add a pre element.
Then we write
const data = {
data: {
x: "1",
y: "1",
url: "http://url.com",
},
event: "start",
show: 1,
id: 50,
};
document.getElementById("json").textContent = JSON.stringify(
data,
undefined,
2
);
to call JSON.stringify with data and 2 to return a JSON string converted from data indented with 2 spaces at each level.
And then we set the textContent of the pre element to the returned JSON string to show it with the indentation.
