Enapso Smart Arguments Processor

You can either pass a single object as arguments or the arguments in the defined order.

Why to use the Enapso Smart Arguments Processor?

You avoid unexpected results due to wrong or missing arguments or due to wrong argument order.
You can specify defaults for missing arguments and valdiate your arguments against a given schema.

}
]
};

function demoSingleStringArg(/text/) {
let args = enGetArgs(arguments, schemaSingleStringArg, logValidationViolation);
console.log('demoSingleStringArg: ' + args.text);
