Explanation / Answer

we can allocate the array for 1000 elements using follwoing syntax
var x = 10;
var myChegg = new Array(100*x);

************************************************************************
creating array in java script
we have two ways
1) by using normal way
   example: var chegg=["std1","std2","std3"];
2) by using javascript method
   example:var chegg = new Array("std1","std2","std3");

********************************************************************************************

decalring and initializg the the array
example
var chegg[]; // declaration
chegg[0]="std1";// initialization
chegg[1]="std2";

*****************************************************************************************************
in javascript when passing the primitive types like string or number it will pass by value
example:
   var y=5;
myChegg(y);

function myChegg(y)
   {
       y=6;
   }
