How can I show the output in console.log?

I am trying to fetch data from an api into console and then display it on a page.

I have correctly fetched the data from the placeholder api into console.log, but I cannot display it onto the page in the div. What am I doing wrong?

fetch('https://jsonplaceholder.typicode.com/todos/1')
  .then(response => response.json())
  .then(json => console.log(json))

document.getElementById("console")
<div id="console"></div>

If you just want to output the data as a formatted string you could create a function to "pretty print" the stringified data using <pre> and <code>.

const output = document.querySelector('.output');

fetch('https://jsonplaceholder.typicode.com/todos/1')
  .then(response => response.json())
  .then(updateHTML);

function updateHTML(data) {
  const json = JSON.stringify(data, null, 2);
  const html = `<pre><code>${json}</code></pre>`;
  output.insertAdjacentHTML('beforeend', html);
}
<div class="output"></div>

If you wanted to display the data differently (in a table, for example) you could iterate (map) over the keys and values returned by Object.entries to return a string of row HTML, and add that html to the page.

const output = document.querySelector('.output');

fetch('https://jsonplaceholder.typicode.com/todos/1')
  .then(response => response.json())
  .then(updateHTML);

function updateHTML(data) {

  // Get the object entries - and array of key/value pairs
  const entries = Object.entries(data);

  // Iterate over the entries and return a new array
  // of strings created from the key/value using a
  // template string.
  const rows = entries.map(([key, value]) => {
    return `
      <tr>
        <td class="heading">${key}</td>
        <td>${value}</td>
      </tr>
    `;
  });

  // Create a new HTML string by `join`ing up the row array
  // and adding it to a new string
  const html = `<table><tbody>${rows.join('')}</tbody></table>`;

  // Insert the HTML into the page
  output.insertAdjacentHTML('beforeend', html);
}
table { background-color: #efefef; border-collapse: collapse; border: 1px solid #afafaf; }
td { padding: 0.4em; border: 1px solid white; }
.heading { text-transform: uppercase; text-align: right; font-weight: 500; background-color: #dfdfdf; }
<div class="output"></div>

innerHTML could achieve.

fetch('https://jsonplaceholder.typicode.com/todos/1')
  .then(response => response.json())
  .then(json => {
  console.log(json);
  document.getElementById("console").innerHTML += JSON.stringify(json)}
  )
