将默认全局对象作为“this”传递给外部javascript模块

我想知道如何将“this”传递到外部模块(脚本.js).

索引.html

<script src='./script.js' defer></script>
<script>
    var interval = setInterval(function () {
        if (document.readyState === 'complete') {
            clearInterval(interval);

            (function (scope) {
                console.log('this inside of function')
                console.log(scope) //this prints 'global {frames: global, ..}
            })(this)  // <<<<< THIS works
        }
    }, 100);
</script>

脚本.js

(function (scope) {
    console.log('this inside of script.js')
    console.log(scope)    /// this prints 'undefined'
})(this)   // << THIS is undefined.
