title: Filter with "&&" condition in array.filter()
body: <p>So people i have 3 checkboxes:</p>
  <pre><code>                    &lt;label&gt;
                          &lt;input type=&quot;checkbox&quot; value=&quot;Java&quot; id=&quot;check-java&quot; class=&quot;check-java filled-in&quot; 
                           /&gt;
                          &lt;span&gt;Java&lt;/span&gt;
                      &lt;/label&gt;
                      &amp;nbsp;
                      &lt;label&gt;
                          &lt;input type=&quot;checkbox&quot; value=&quot;JavaScript&quot; id=&quot;check-javascript&quot; class=&quot;check-javascript filled-in&quot; /&gt;
                          &lt;span&gt;JavaScript&lt;/span&gt;
                      &lt;/label&gt;
                      &amp;nbsp;
                      &lt;label&gt;
                          &lt;input type=&quot;checkbox&quot; value=&quot;Python&quot; id=&quot;check-python&quot; class=&quot;check-python filled-in&quot;
                               /&gt;
                          &lt;span&gt;Python&lt;/span&gt;
                      &lt;/label&gt;
  </code></pre>
  <p>And when a user select this checkboxes i catch it in an eventListener`:</p>
  <pre><code>const checkBoxes = document.querySelectorAll('input[type=checkbox]');
  checkBoxes.forEach((box) =&gt; {
      return box.addEventListener('change', filterByCheckBox)
  });
  </code></pre>
  <p>So, when the user select two or more of this checkboxes i need to filter an array (devsFiltered), there contains a  sub-array called &quot;programmingLanguages&quot; and in this array i have 3 possible values &quot;Java,JavaScript or Python&quot; and i need to filter only if the array contains the two or more values selected by the checkboxes, the code i'm trying to use:</p>
  <pre><code>function filterByCheckBox(e) {
                  const checkOption = e.target.value;
                  if (devsFiltered.length &gt; 0) {
                      const filtered  = devsFiltered
                      .filter(item =&gt; item.programmingLanguages
                          .every(lang =&gt; lang.language == checkOption));
                           mapUsers(filtered)
                  }
          }
  </code></pre>
