I want to print the followers in my webpage, it shows up in the console, but not the html document. the code:

async function getFollowers(user) {
      const response = await fetch(`https://scratchdb.lefty.one/v3/user/info/${user}`);
      let responseJson = await response.json();
      const count = document.getElementById.innerHTML("123");
      count = responseJson.statistics.followers;
      return count;}

function pfollows(user) {
   const element = document.getElementById.innerHTML("123");
   const USER = user;
   getFollowers(USER).then(count => {
      element.textContent = `${USER} has ${count} followers right now.`;
   });
}
javascript

document.getElementById.innerHTML("123") seems wrong.

You should be passing an id as a string to document.getElementById like document.getElementById("someIdHere"). innerHTML is not a function and shouldn't have parentheses or an argument after it.

count looks like it should be extracted from responseJson and returned.

pfollows looks like it might be responsible for updating the actual DOM.

Redefining user as USER is somewhat redundant.

async function getFollowers(user) {
      const response = await fetch(`https://scratchdb.lefty.one/v3/user/info/${user}`);
      let responseJson = await response.json();
      const count = responseJson.statistics.followers;
      return count;
}

function pfollows(user) {
   const element = document.getElementById("123").innerHTML;
   getFollowers(user).then(count => {
      element.textContent = `${user} has ${count} followers right now.`;
   });
}

When pfollows is called, then the element with id="123" should have its content set to the desired string. If pfollows() is not called, then nothing will happen.

There's a few more possible touchups to clean up:

  • responseJson can probably be a const
  • You can inline return count without saving it to a variable return responseJson.statistics.followers

but trying to keep the changes minimal as needed to fix the problems.
