Arguments

The Arguments object returns an Object object containing all arguments passed to a function. It is useful for creating functions that can intake an undetermined amount of arguments to process.

Access the object indexes like we access array indexes. function myFunction() { return arguments[0]+" | "+arguments[1]+" | "+arguments[2]; }

 

var result = myFunction(100, false, "hello");

 

alert(result);

 

Use a for loop or similar loop statement to iterate over the entire list of arguments. function sum(){

 

var result = 0;

 

for( i = 0; i < arguments.length; i++ ){

 

result += arguments[i];

 

} return result;

 

}

 

alert( sum(10, 5, 2, 3, 10) );
