Consider the following code snippet :

var string2Num=parseInt("123xyz");

2) A function with no return value is called

3) What is the difference between the two lines given below ?

  !!(obj1 && obj2); (obj1 && obj2);

4) Consider the following code snippet :

function constfuncs()
  {
     var funcs = [];
     for(var i = 0; i < 10; i++)
         funcs[i] = function()
 {
 return i;
 };
     return funcs; }
 var funcs = constfuncs();
 funcs[5]()

5) What will happen if a return statement does not have an associated expression?
