Why the browser doesn't see my module?
Question
Google Chrome 58.0.3029.110 (64-bit)
ECMAScript 6
I learn JavaScript and read the Understanding ECMAScript 6 book. ECMAScript 6 defines the module conception.
I wrote couple js-files and attached them into my html file. One of them is script and other is the module. But Google Chrome doesn't see my js-module. Why does it happen?
This is my html:
<!DOCTYPE html>
<html>
<head>
<meta charset='utf-8'/>
<title>Sandbox</title>
<script src='./js/module.js' type='module'></script>
<script src='./js/script.js' type='text/javascript'></script>
</head>
<body>
</body>
</html>
This is my script:
/* ECMAScript 6
* ./js/script.js
*/
function scriptFunction(){
console.log('I am script function!');
}
This is my module:
/* ECMAScript 6
* ./js/module.js
*/
function internalFunction(){
console.log('I am internal!');
}
export function exportedFunction(){
console.log('I am exported!');
}
This is the result:

Modules are not yet supported by most browsers. Safari 10.1 implements them. In Chrome Canary you need to enable support as explained by @SkinnyJ.
But still you'll have to fix some issues in your code:
<!DOCTYPE html>
<html>
<head>
<meta charset='utf-8'/>
<title>Sandbox</title>
<script src='./js/module.js' type='module'></script>
<script src='./js/script.js' type='module'></script>
</head>
<body>
</body>
</html>
/* ECMAScript 6
* ./js/module.js
*/
function internalFunction() {
console.log("I am internal!");
}
export function exportedFunction() {
internalFunction();
console.log("I am exported!");
}
/* ECMAScript 6
* ./js/script.js
*/
import {exportedFunction} from "./module.js";
function scriptFunction() {
console.log("I am script function!");
}
scriptFunction();
exportedFunction();
This works in Safari 10.1 and Chrome Canary with chrome://flags/#enable-experimental-web-platform-features enabled.

ES6 modules are currently available in Chrome Canary behind the "Experimental Web Platform" flag. They are not available in "stable" Chrome.
