How can I edit the div that is clicked when all other divs have the same className?

Question

How can I access the div which is currently clicked, when all the divs have the same name? innerNote contains the text of each note. Each note is made up of a parent div and a child div (innerNote), which are created dynamically.

When I have multiple notes and click on the edit icon of a single note and save changes, all the notes get added with the same text. Is there a way I can edit the text of only the clicked div rather than all the divs?

let add_btn = document.querySelector('.add');
let container = document.querySelector('.container');
let createNote = document.querySelector('.create-note');
let create = document.querySelector('.create-btn');
let close = document.querySelector('.close-btn');
let text = '';
let editNote = document.querySelector('.edit-note');
let textArea = document.querySelector('textarea');
let closeBtn = document.querySelector('.close-btn2');
let editBtn = document.querySelector('.edit-btn');
let textArea2 = document.querySelector('.textarea2');

add_btn.addEventListener('click', () => {
  textArea.value = '';
  createNote.style.display = 'block';
})

close.addEventListener('click', () => {
  createNote.style.display = 'none';
})

create.addEventListener('click', () => {
  let note = document.createElement('div');
  note.className = 'note';
  
  let innerNote = document.createElement('div');
  innerNote.className = 'inner-note';
  text = textArea.value;
  innerNote.textContent = text;
  
  let edit = document.createElement('i');
  edit.className = 'fa-solid fa-edit';
  
  let del = document.createElement('i');
  del.className = 'fa-solid fa-trash';
  
  if (!textArea.value) {
    return;
  } else {
    note.appendChild(innerNote);
    note.appendChild(edit);
    note.appendChild(del);
    container.appendChild(note);
    createNote.style.display = 'none';
    note.style.display = 'block';
    edit.addEventListener('click', () => {
      textArea2.value = text;
      editNote.style.display = 'block';
    })
    
    editBtn.addEventListener('click', () => {
      let currentDiv = innerNote;
      currentDiv.textContent = textArea2.value;
      editNote.style.display = 'none';
    })
    
    del.addEventListener('click', () => {
      container.removeChild(note);
    })
  }
});

closeBtn.addEventListener('click', () => {
  editNote.style.display = 'none';
})

You need to delegate

I had to comment out the container height to make the box visible in viewport

let add_btn = document.querySelector('.add');
let container = document.querySelector('.container');
let createNote = document.querySelector('.create-note');
let create = document.querySelector('.create-btn');
let close = document.querySelector('.close-btn');
let text = '';
let editNote = document.querySelector('.edit-note');
let textArea = document.querySelector('textarea');
let closeBtn = document.querySelector('.close-btn2');
let editBtn = document.querySelector('.edit-btn');
let textArea2 = document.querySelector('.textarea2');

add_btn.addEventListener('click', () => {
  textArea.value = '';
  createNote.style.display = 'block';
})

close.addEventListener('click', () => {
  createNote.style.display = 'none';
})

create.addEventListener('click', () => {
  let note = document.createElement('div');
  note.className = 'note';

  let innerNote = document.createElement('div');
  innerNote.className = 'inner-note';
  text = textArea.value;
  innerNote.textContent = text;

  let edit = document.createElement('i');
  edit.className = 'fa-solid fa-edit';

  let del = document.createElement('i');
  del.className = 'fa-solid fa-trash';

  if (!textArea.value) {
    return;
  } else {
    note.appendChild(innerNote);
    note.appendChild(edit);
    note.appendChild(del);
    container.appendChild(note);
    createNote.style.display = 'none';
    note.style.display = 'block';
  }
});


editBtn.addEventListener('click', () => {
  currentDiv.textContent = textArea2.value;
  editNote.style.display = 'none';
})


container.addEventListener('click', (e) => {
  const tgt = e.target;
  if (!tgt | (!tgt.matches('.fa-edit') && !tgt.matches('.fa-trash'))) return;

  const parent = tgt.closest('div.note');
  if (tgt.matches('.fa-edit')) {
    currentDiv = parent.querySelector('.inner-note');
    textArea2.value = currentDiv.textContent;
    editNote.style.display = 'block';
  }
  if (tgt.matches('.fa-trash')) {
    container.removeChild(parent);
  }
})
closeBtn.addEventListener('click', () => {
  editNote.style.display = 'none';
})
