Why the need to place getElementById at bottom?

Recommended Posts

Stef

No definitive reason was given as to why its best practice to place getElementById at the bottom of document when used together with anonymous functions in lesson 6 chapter 2.

Would anything be different if it was placed higher up in the document?

I would have to see the context of the video. That said, remember that JS is read from the top down. So this means you have to be sure code is read into memory before you call it. So if you have inline JS (not in a function) that is calling getElementById on a tag that has not been read into memory, you will get an error.
