JS Wickeln Sie eine Funktionsparameter für Funktionen in die Funktion
function fnOriginal(a){
console.log(1/a);
};
var fn2 = makeSafe(fnOriginal);
fn2(1);
fn2(0);
fn2("abracadabra!");
var obj = {
method1: function(x){ /* do something */ },
method2: function(x){ /* do something */ }
};
obj.safeMethod1 = makeSafe(obj.method1);
obj.method1(42); // the original method
obj.safeMethod1(42); // the "safe" method
// let's override a method completely
obj.method2 = makeSafe(obj.method2);
