Maximizing the number of parameters through JavaScript

Maximizing the number of parameters through JavaScript

Hi Jessica,

Inside every function, we have an object called an arguments array. It is this object that stores and calculates how many parameters you are passing on to the function. This array is present in every function even if we do not declare this or demand it.

With the help of the arguments array and some minor changes in defining the functions we create, we can make a function that accepts any number of parameters.

Instead of the normal function with parameters,

function hello(x,y,z){

}

We create a function as so:

function hello(){

}

See that the function we created above no longer has any parameters. Then we just create a loop inside the function we made:

function hello(){

for (x=0;x<hello.arguments.length;x++)

//do whatever

}



Thanks Jessica, hope this would be of help.
