La propietat function.arguments es refereix a un objecte que s'assembla a una array corresponent als arguments passats a una funci贸. Utilitzeu la variable simple arguments.


La sintaxis function.arguments 茅s obsoleta. El cam铆 recomanat per accedir a l'objecte arguments disponible en les funcions requereix simplement referir-se a la variablearguments.

En cas de recursivitat, 茅s a dir, si la funci贸 f apareix v脿ries vegades en la pila de crides, el valor det f.arguments representa els arguments corresponents a la invocaci贸 m茅s recent de la funci贸.

El valor del la propietat arguments normalment 茅s null si no hi ha una invocaci贸 excel路lent de la funci贸 (aix貌 vol dir, que s'ha cridat la funci贸 per貌 la seva execuci贸 encara no s'ha acabat).


function f(n) { g(n - 1); }

function g(n) {
  console.log('before: ' + g.arguments[0]);
  if (n > 0) { f(n); }
  console.log('after: ' + g.arguments[0]);


console.log('returned: ' + g.arguments);

// Resultat

// abans: 1
// abans: 0
// despr茅s: 0
// despr茅s: 1
// retorn: null
