Hey @kartik,

Scope Parameter is a collection of various symbol that is used to  communicate between isolated scope and its parent scope.

The Various Scope Parameter are- {@,=,&}

1. @

•        It is used to pass the string value to the directive scope
•        One way to the directive scope
•        String could be interpolate string.

2.=

•        It is used to pass an object to the directive scope.
•       Two way binding between parent and directive scope

3.&

•       It is used to enable function to be access to its directive scope. 
•      Directive can executed the function passed to it.

There is another way to communicate between isolated scope and its parent scope simply by using $parent but this is not good practice to access data of parent scope.
