click twice?

Hi,

I've added a toggle function to my portfolio site on small screens, but it seems like there is a problem because to show the list you need to click the button 2 times.

Any idea why?

const toggleList = document.querySelector('#toggleList');
const projectList = document.querySelector('#projectList');
const weaterList = document.querySelector('.weather-list');
const quoteList = document.querySelector('.quote-list');
const wikiList = document.querySelector('.wiki-list');
const rpsList = document.querySelector('.rps-list');
const weatherApp = document.querySelector('.weather-app');
const quoteApp = document.querySelector('.quote-app');
const wikiApp = document.querySelector('.wikipedia-app');
const rpsApp = document.querySelector('.rps-app');

toggleList.addEventListener('click', () => {
  if (projectList.style.display == 'none') {
    toggleList.textContent = 'Hide Projects';
    projectList.style.display = 'block';
  } else {
    toggleList.textContent = 'Show Projects';
    projectList.style.display = 'none';
  }
});

// toggle between projects on small screens
projectList.addEventListener('click', (e) => {
  if (e.target == weaterList) {
    quoteApp.style.display = 'none';
    wikiApp.style.display = 'none';
    rpsApp.style.display = 'none';
    weatherApp.style.display = 'block';
  }
  if (e.target == quoteList) {
    weatherApp.style.display = 'none';
    wikiApp.style.display = 'none';
    rpsApp.style.display = 'none';
    quoteApp.style.display = 'block';
  }
  if (e.target == wikiList) {
    weatherApp.style.display = 'none';
    quoteApp.style.display = 'none';
    rpsApp.style.display = 'none';
    wikiApp.style.display = 'block';
  }
  if (e.target == rpsList) {
    weatherApp.style.display = 'none';
    quoteApp.style.display = 'none';
    wikiApp.style.display = 'none';
    rpsApp.style.display = 'block';
  }
});

<button id="toggleList" class="btn btn-primary center-block">Show Projects</button>
        <div id="projectList" class="row">
          <div class="col-xs-4 col-xs-offset-4 btn btn-primary weather-list lists">WeaterApp</div>
          <div class="col-xs-4 col-xs-offset-4 btn btn-primary quote-list lists">QuoteApp</div>
          <div class="col-xs-4 col-xs-offset-4 btn btn-primary wiki-list lists">WikiApp</div>
          <div class="col-xs-4 col-xs-offset-4 btn btn-primary rps-list lists">Rock...App</div>
        </div>

:point_right: It works every time for me.

The only oddity I noticed is that it says "Show Projects" before and after the first click, but that's just because of the initial text in the HTML. It should probably start out as "Hide Projects".

How are you testing it? Anything unusual there?

Hmm.. That's odd - I only experience the double-click issue (and only the first time)

Right now I'm just testing by opening the file in the browser -> open the chrome dev tool -> setting view to iPhone 5 -> then clicking the button.
