我刚刚完成了关于 javascript 的代码学院课程，但它没有教我如何在 html 中编写 javascript。我需要使用该函数在 html 的标签内显示 hello world 这可能吗？我的朋友告诉我我需要 jquery 来做到这一点。

You have to specifically tell the webpage to execute your function when it's loaded.
您必须明确告诉网页在加载时执行您的功能。
Instead of returning the string I believe you'd like to write it in the body of the webpage.
我相信您希望将它写在网页正文中，而不是返回字符串。
This is a simple way to do so :
这是一个简单的方法：
<html>
<head>
<script>
var myFunction = function(){
document.body.innerHTML = "hello world";
}
</script>
</head>
<body onload='myFunction();'>
</body>
</html>
