为什么我的插入脚本标签不可见？

Question

I'm loading a block of script tags with a for loop from a js file. That works as functions are called, but I don't understand why the script tags are not on the document in source view.

For example:

for (var str in library) {
    document.write("<script src='" + "scriptsfolder/" + "" + library[str] + "'></script>");
}

Where are those scripts written to? And why does this work?

The for loop is called after js file is loaded.

Most browsers, when using "View Source", make a new request to the server to fetch the HTML for the page, and do not execute JavaScript. Use the browser's debugger/inspector (eg right click -> "Inspect Element" in Chrome) and you will see your new script tags.
