これは <script> 要素の src 属性を反映したものです。

html
<script id="script-with-src" type="module" src="/main.js"></script>
<script id="script-without-src" type="module"></script>
js
const script_with_src = document.getElementById("script-with-src");
console.log(script_with_src.src); // 出力: "https://example.com/main.js"
const script_without_src = document.getElementById("script-without-src");
console.log(script_without_src.src); // 出力: ""
