   // 1) What is the purpose of the 'this keyword'?
 
       //Answer
+      //When a function is called with the new operator, 'this' refers to the newly created object inside that function.
 
   // 2) What are the four rules that govern what the 'this keyword' is bound to and describe each?
 
       //Answer
+      //- Implicit Binding - this happens when dot notation is used to invoke a function
+      //- Explicit Binding - this happens when call, apply, or bind are used on a function
+      //- new binding - this has the highest priority
+      //- Default Binding -the most common case of function calls the standalone function invocation
 
   // 3) What does .bind do?
 
       //Answer
+      //The bind method allows you to attach an object to a function and then reference the attached object using the 'this' keyword
