I am using Winston (Logger for nodejs).
In my script i call:
log.error("my error", {input: [1,2]});
console show me:
error: my error input=[1, 2]
What i want to do: don' call at log.error(null)
In some functions i dynamically call the log.error with a variable and dont know if the variable are NULL or have a value. If i call log.error(null) he write "error:" to the console.
I tried with this:
log.error = (function () {
var old = log.error;
return function newerror() {
if (arguments.length !== 0) {
old(arguments);
}
};
})();
But now i got:
error: 0=my error, input=[1, 2]
as output.
My Question
how i can call the log.error() function with die arguments given (arguments-var in javascript is a object).
Function style:
function foo(arg1,arg2,...)
I want something like:
foo.call(myargumentsobj);
