ESLint has added JSON and Markdown linting support with new officially-supported plugins, expanding its versatility beyond JavaScript.
variable argument handling for functions taking a callback
JavaScript has very poor argument handling. vargs tries to make it simpler.
var Args = require("vargs").Constructor;
function (/* [arg1, arg2, ...][,callback] */) {
var args = new(Args)(arguments);
args.first; // first argument
args.last; // last argument before callback
args.callback; // callback argument, or an empty function
args.all; // all arguments except callback
args.length; // number of arguments, not including callback
args.callbackGiven(); // returns true or false
args.at(-1); // last argument, including callback
args.array; // all arguments, including callback
}
