Putting JavaScript at the end of the page results in an error

I recently read that for faster webpage loading, it is good practice to put JavaScript links at the end. I did, but now the link file functions are not working. If I put the link at the top of the page, everything will be fine.

Is this thing to install javascript at the end of the job only under certain circumstances?

I also went through testing. If you download a Javascript file, it’s faster to put it at the end, but it contains some important caveats.

It appears that Yahoo Practice is roughly "the library code at the beginning of <body>, the active code at the end of <body>."

Beware, however, this can lead to Flash of Unstyled Content Syndrome .
