class test {
constructor() {
console.log("init");
}
}
module.exports = test;<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>drawBoard</title>
</head>
<body>
</body>
<script type="text/javascript" src="../build/test.js"></script>
<script type="text/javascript">
console.log(typeof test) // undefined
</script>
</html>Such a direct call will definitely fail.
I looked at the packaged code of webpack, and my understanding is that an anonymous function is packaged, and then the class of module.exports is returned in the anonymous functiontest.
You can use import to write with es6, but how to call it with es5?
Please explain, thank you.
