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?
回答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.
