JavaScript function/onclick not working

<h4 id="myH4">?????</h4>
<button id="myButton" onclick="myButton">Click Here!</button>
<script>
document.getElementById("#myButton").onclick = function(){
	const h4 = document.getElementById("#myH4");
	h4.innerText = "$59,343";
}

You are not providing the correct id name to document.getElementById,

I’m trying to change style of an element, and it’s not functioning

By my guess, everything inside the curly braces.
