JSON.people is undefined. How do I fix this?

It will be easier to help if we can see your code. You might want to take a look at this video about Posting a Question. And for when your question refers to something you are doing in a workspace, you may also want to view this one about sharing a snapshot of your workspace.

Here's my code.

const astrosUrl = 'http://api.open-notify.org/astros.json'; const wikiUrl = 'https://en.wikipedia.org/api/rest_v1/page/summary/'; const peopleList = document.getElementById('people'); const btn = document.querySelector('button');

// Make an AJAX request function getJSON(url, callback) { const xhr = new XMLHttpRequest(); xhr.open('GET', url); xhr.onload = () => { if(xhr.status === 200) { let data = JSON.parse(xhr.responseText); return callback(data); } }; xhr.send(); }

// Generate the markup for each profile function generateHTML(data) { const section = document.createElement('section'); peopleList.appendChild(section); // Check if request returns a 'standard' page from Wiki if (data.type === 'standard') { section.innerHTML = <img src=${data.thumbnail.source}> <h2>${data.title}</h2> <p>${data.description}</p> <p>${data.extract}</p> ; } else { section.innerHTML = <img src="img/profile.jpg" alt="ocean clouds seen from space"> <h2>${data.title}</h2> <p>Results unavailable for ${data.title}</p> ${data.extract_html} ; } }

btn.addEventListener('click', () => { getJSON(astrosUrl, (json) => { JSON.people.map(person => { getJSON(wikiUrl + person.name, generateHTML); }); }); });

A snapshot allows your entire working environment to be replicated, which will include the HTML part which your program needs to run. Please use that whenever asking about workspace code.

And when posting non-workspace code, at least be sure to use Markdown formatting to preserve the code's appearance.

Steven Parker...thankyou for the lower case json suggestion. It worked.
