I have done something similar to this before, and I know this is really close. I'm just trying to make it so that my button increments the javascript variable, and the function then displays the new value.

<html>
<head>
    <title>Space Clicker</title>
</head>

<body>
    <script type="text/javascript">
    int clicks = 0;
    function click() {
        clicks += 1;
        document.getElementById("clicks").innerHTML = clicks;
    };
    </script>
    <button type="button" onClick="click()">Click me</button>
    <p>Clicks: <a id="clicks">0</a></p>

</body></html>

Don't use the word "click" as the function name. It's a reserved keyword in JavaScript. In the bellow code I’ve used "hello" function instead of "click"

<html>
<head>
    <title>Space Clicker</title>
</head>

<body>
    <script type="text/javascript">

    var clicks = 0;
    function hello() {
        clicks += 1;
        document.getElementById("clicks").innerHTML = clicks;
    };
    </script>
    <button type="button" onclick="hello()">Click me</button>
    <p>Clicks: <a id="clicks">0</a></p>

</body></html>

After looking at the code you're having typos, here is the updated code

var clicks = 0; // should be var not int
    function clickME() {
        clicks += 1;
        document.getElementById("clicks").innerHTML = clicks; //getElementById() not getElementByID() Which you corrected in edit
 }

Demo

Note: Don't use in-built handlers, as .click() is javascript function try giving different name like clickME()

Through this code, you can get click count on a button. 

<!DOCTYPE html>
<html>
<head>
    <meta charset="utf-8">
    <title>Button</title>
    <link rel="stylesheet" type="text/css" href="css/button.css">
</head>
<body>
    <script src="js/button.js" type="text/javascript"></script>

    <button id="btn" class="btnst" onclick="myFunction()">0</button>
</body>
</html>
 ----------JAVASCRIPT----------
let count = 0;
function myFunction() {
  count+=1;
  document.getElementById("btn").innerHTML = count;

 }

Use var instead of int for your 'clicks' variable generation and 'onClick' instead of 'click' as your function name:

<html>
<head>
    <title>Space Clicker</title>
</head>

<body>
    <script type="text/javascript">
    var clicks = 0;
    function onClick() {
        clicks += 1;
        document.getElementById("clicks").innerHTML = clicks;
    };
    </script>
    <button type="button" onClick="onClick()">Click me</button>
    <p>Clicks: <a id="clicks">0</a></p>

</body></html>

In JavaScript variables are declared with the 'var' tag, there are no tags like int, bool, string... to declare variables. You can get the type of an variable with 'typeof(yourvariable)', more support about this you find on Google.

And the name 'click' is reserved by JavaScript for functionnames so you have to use anything else.

    function myFunction() {

        clicks += 1;
        document.getElementById("demo").innerHTML = clicks;


    }
</script>
</head>
<body>

<p>Click the button to trigger a function.</p>

<button onclick="myFunction()">Click me</button>

<p id="demo"></p>

</body>
</html>
