HTML/Javascript Button Click Counter

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>

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

var clicks = 0;

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

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

And the name 'click' is reserved by JavaScript for function names so you have to use something else.

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;

 }

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>

    <!DOCTYPE html>
<html>
<head>
<script>
     var clicks = 0;
    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>

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()
