What does the value of $ in javascript function name mean?

Question

GWT displays the codes as follows:

function com_mycompany_mywebapp_client_CTest_$$init__Lcom_mycompany_mywebapp_client_CTest_2V(){
this$static}

What does the meaning of $ mean, or is it just another character, like an underscore? Will this_static mean the same thing?

Answer 1

Nuthin. This is just a character. Think of it as an S with a stick stuck in it.

Answer 2

A dollar sign has been added for use in machine characters so that they do not interfere with hand-written characters. But syntactically, it is just like underlining; it does not mean anything special.
