Variable naming conventions other than trailing underscore [duplicate]

Question

This question already has answers here:

JSLint reports "Unexpected dangling" character in an underscore prefixed variable name (4 answers)

Closed 6 years ago.

I'm reformatting a plug-in so that it passes JSLint. Plug-in uses trailing underscores to name local variables, like so:

var __slice = [].slice,
    __indexOf = [].indexOf

JSLint does not like this. What's another easily recognisable convention for naming these, that JSLint won't object to?

Answer 1

Quoting from Douglas Crockford, the guy who invented JSLint:

Do not use _ (underbar) as the first character of a name. It is sometimes used to indicate privacy, but it does not actually provide privacy. If privacy is important, use the forms that provide private members. Avoid conventions that demonstrate a lack of competence.

Most variables and functions should start with a lower case letter.

Taken from Code Conventions for the JavaScript Programming Language .

You can look at Private Members in Javascript to see what he meant by use the forms that provide private members.
