javascript - What is the use of comments like <!--headTrap--><!--tailTrap> on WeChat public accounts?

Question

When I looked at the source code of the WeChat official account article page, I found that
had such comments at the beginning and end

##What is this for? Is there any specific use?

Answer 1

It’s useless.

Really.

Answer 2

Is there some logo automatically generated by the editor written in the background? This kind of public account article usually has an editor manager or something. The person who wrote it made it. I don’t know the specific function, so visual inspection is useless.

Answer 3

should be a trap character for the build tool,

Answer 4

Don’t worry about such details. To be honest, I have seen meta uft8 used twice in a row on the homepage of a well-known e-commerce company. They are still exactly the same and adjacent.
