In theory, yes. But if you follow the link and that leads to downloading the JS and running it, you’re already too late inspecting it.
And even if you review it once (and it wasn’t too large or obfuscated via minification), the next time you load a page, the JS can be different. I guess there could be a web browser extension for pinning the code?
The only practial alternative I know of is to have a local client you can review once (and after updates).
But the JS code could be checked on the webpage, correct? If so, the page could be trysted (if vetted).
