I want to use javascript to print the username of username in here. It can either iterate through each thing and print the username value, or it can just take the first value because that is the username too. I can't find a good tutorial online anywhere for this. I want to make sure that I print every username and not entity. Can someone please help with this?
Assuming your JSON variable is called data, you can extract the keys with Object.keys(data)
To iterate and get the usernames you can do
Object.keys(data).forEach(key => {
let username = data[key].username;
});
