It's not about jQuery. When i read the source code of events.js in Node.js,i found that:

One of my guess is the function $getMaxListeners is used twice ,the second time it is used is after several lines.

i knew the '_' prefix is a convention which represents private. so is there any convention of '$' prefix?

$ is just a character of the method's name in this case – Héctor May 08 '18 at 09:34

It's just a character, no special meaning. – Teemu May 08 '18 at 09:34
Seems to describe the pure `function` to be used on `prototype` here. For the `prototype` the version without `$` is used. – deEr. May 08 '18 at 09:35

I've only ever seen the dollar prefix used for third-party libraries. – evolutionxbox May 08 '18 at 09:36

@Tushar is there a case for this being a dupe? – evolutionxbox May 08 '18 at 09:37
