The JavaScript arguments object is a local variable available within all functions. It contains all the function parameters that are passed to the function and can be indexed like an array. The length property of the arguments object returns the number of arguments passed to the function.

JavaScript arguments object example :
function printArguments()
{
{
}
}

printArguments();
printArguments("A", "B");
printArguments(10, 20, 30);

Is it possible to pass variable number of arguments to a JavaScript function
Yes, you can pass as many arguments as you want to any javascript function. All the parameters will be stored in the arguments object.

function addNumbers()
{
var sum = 0;
{
sum = sum + arguments[i];
}
}

addNumbers();
addNumbers(10, 20, 30);

The arguments object is available only inside a function body. Attempting to access the arguments object outside a function results in 'arguments' is undefined error. Though you can index the arguments object like an array, it is not an array. It does not have any Array properties except length. For example it does not have the sort() method, that the array object has. However, you can convert the arguments object to an array.

Converting JavaScript arguments object to an array
function numbers()
{
}

numbers(50, 20, 40);

Output : 20, 40, 50

Converting JavaScript arguments object to an array using array literals
function numbers()
{
}

numbers(50, 20, 40);

Output : 20, 40, 50

previous video, you have mentioned with sort(), for integers we need to call function (a-b) for ascending and (b-a) for descending.how you got elements sorted in this video without that functionality.can you please explain

[girlandhercomputer]

I really like you calming voice, very very clear explanation, my tons of respects to you!

FINALLY! FINALLY I got the concept of closures! Thank you!!

[jarlorm]

thanks for dumbing it down for people like me :)

Cool point about how the argument object is only available inside the body of a function.

[anishbapat]

Sir to this sort method if we pass values 100, 20, 10
we get wrong output as 10, 100, 20
instead of 10, 20, 100

[McGavel]

That was a cool trick using the Array Literal.

1.How "Arguments" will work in closures....??
2.How did the sort() function work for integers

[KLNNNN]

why slice.call? slice makes a copy of the original array, while call changes the context of the this keyword
