I want each button to repeat its value from 0 when it is clikced [closed]

const buttons = document.querySelectorAll('.addButton');
let initialVal = buttons.value = 0

function add() {
  let inc = parseInt(initialVal++)
  console.log(inc);
}

<button class="addButton" value="0" onclick="add()">Add</button>
<button class="addButton" value="0" onclick="add()">Add</button>
<buttonclass="addButton" value="0" onclick="add()">Add</button>

Expected Output

button1 clicked
output: 0,1,2,3,4

button2 clicked
output:0,1,2,3,4

my current output :

button1 :0,1,2
button2 :3,4,5...
