Do not declare function and variable with the same name in same scope

In Javascript functions and variables share same namespace  and that is why this code will break



        function ThisIsAFunction(n) {




        var ThisIsAFunction = 'India';


        alert('abount to execute');





Basically 1st statement in code is similar to

var ThisIsAFunction  = function ThisIsAFunction(n) { alert(n); };




var ThisIsAFunction = = function (n) { alert(n); };


and this will collide even inside a closure as closure will be scope rather than global.
