Call your function anything other than alert. It's a reserved keyword, and the error your code gives you is:

InternalError: too much recursion

function handleClick() {
  alert('working...');
}

<button type="button" onclick="handleClick()">Want a greeting?</button>

alert() is a built-in method of JavaScript.

If you change the name of your function that will fix the issue:

function test(){ alert('working...') }

<button type="button" onclick="test()">Want a greeting?</button>

You can override the alert method but you can't recursively call the same function. The issue you're running into is an infinite recursion, you're calling alert > alert > alert > alert > ...

Something like this would work, though.

window.alert = function alert(message){ console.log(message) }

<button type="button" onclick="alert('test')">Want a greeting?</button>

<button type="button" onclick="click()">Want a greeting?</button>

<script> let click = () => {alert('working...');}</script>
