How can I create a button that increments a counter when clicked?

Question

I am trying to make a button that increments a counter's value by 1 when clicked. My code, however, doesn't seem to work.

var count = 1;
var button = document.querySelector("#increment");

button.addEventListener("click", function() {
  var increment = document.getElementById("#count");
  increment.value = count;
  count++;
});

<h4>Current count: <span id="count">0</span></h4>
<div class="container">
  <button id="decrement">Decrement</button>
  <button id="increment">Increment</button>
</div>

You don't need # in getElementById and use innerHTML to set value. Don't use querySelector when you can get by id.

Like this:

let count = 0;
const button = document.getElementById("increment");
const button2 = document.getElementById("decrement");
const textHolder = document.getElementById("count");
textHolder.innerHTML = count;

button.addEventListener("click", function() {
  textHolder.innerHTML = ++count;
});

button2.addEventListener("click", function() {
  textHolder.innerHTML = --count;
});

<h4>Current count: <span id="count">0</span></h4>
<div class="container">
  <button id="decrement">Decrement</button>
  <button id="increment">Increment</button>
</div>
