web如何引入js文件路径

<script>
  console.log("Hello, World!");
</script>

<script src="path/to/your/script.js"></script>

function loadScript(url, callback) {
  var script = document.createElement("script");
  script.type = "text/javascript";
  if (script.readyState) { // IE
    script.onreadystatechange = function() {
      if (script.readyState == "loaded" || script.readyState == "complete") {
        script.onreadystatechange = null;
        callback();
      }
    };
  } else { // Others
    script.onload = function() {
      callback();
    };
  }
  script.src = url;
  document.getElementsByTagName("head")[0].appendChild(script);
}

loadScript("path/to/your/script.js", function() {
  console.log("Script loaded and ready!");
});

<script type="module" src="path/to/your/module.js"></script>

export function greet(name) {
  console.log(`Hello, ${name}!`);
}

import { greet } from './module.js';
greet('World');

<script src="main.js" defer></script>

<script src="script.js?v=1.0.1"></script>
